This is a backport of a fix applied in 5.1.32 into 5.1.31sp1 

The original fix was done by Jonathan Perkin and committed by Georgi Kodinov
on 2009-02-10.
The same day, Georgi added a compilation fix which is already included here.


Original comment:
  Merge libedit 2.11 and related files,
  based on NetBSD CVS as of 2009/02/06 20:09:00.

An approximate method to merge from upstream is:
# Fetch latest from upstream (we also include some compat stuff)
$ CVS_RSH=ssh; export CVS_RSH
$ CVSROOT="anoncvs@stripped:/cvsroot"
$ cvs co -d libedit -P src/lib/libedit
$ mkdir libedit/np
$ for f in src/common/lib/libc/string/strlcat.c \
> src/common/lib/libc/string/strlcpy.c \
> src/include/vis.h \
> src/lib/libc/gen/unvis.c \
> src/lib/libc/gen/vis.c \
> src/tools/compat/fgetln.c
> do
> cvs co -P ${f}
> mv ${f} libedit/np
> done
$ rm -rf src
$ cd libedit
# Remove files we don't need/use
$ rm -rf CVS TEST Makefile shlib_version *.[0-9]
$ (cd readline; rm -rf CVS Makefile)
# Rename files to match our naming
$ mv makelist makelist.sh
$ mv term.h el_term.h
# Remove NetBSD-specific bits
$ for file in $(find . -type f)
> do
> cp ${file} ${file}.orig
> sed -e 's/#include "term.h"/#include "el_term.h"/g' \
> -e 's/sig_handler/el_sig_handler/g' \
> -e 's/isprint/el_isprint/g' \
> -e '/^__RCSID/d' \
> ${file}.orig >${file}
> rm ${file}.orig
> done
then merge remaining bits by hand. All MySQL-specific changes should be
marked with XXXMYSQL to make them easier to identify and merge. To generate
a 'clean' diff against upstream you can use the above commands but use
cvs co -D "2009/02/06 20:09:00" [..]
to fetch the baseline of most recent merge.
Please feed any fixes to Jonathan Perkin <jperkin@stripped> who will endeavour
to merge them upstream and keep diffs minimal.

.Sh DESCRIPTION
The
.Nm
library provides generic line editing and history functions,
similar to those found in
.Xr sh 1 .
.Pp
These functions are available in the
.Nm libedit
library (which needs the
.Nm libtermcap
library).
Programs should be linked with
.Fl ledit ltermcap .
.Sh LINE EDITING FUNCTIONS
The line editing functions use a common data structure,
.Fa EditLine ,
which is created by
.Fn el_init
and freed by
.Fn el_end .
.Pp
The following functions are available:
.Bl -tag -width 4n
.It Fn el_init
Initialise the line editor, and return a data structure
to be used by all other line editing functions.
.Fa prog
is the name of the invoking program, used when reading the
.Xr editrc 5
file to determine which settings to use.
.Fa fin ,
.Fa fout
and
.Fa ferr
are the input, output, and error streams (respectively) to use.
In this documentation, references to
.Dq the tty
are actually to this input/output stream combination.
.It Fn el_end
Clean up and finish with
.Fa e ,
assumed to have been created with
.Fn el_init .
.It Fn el_reset
Reset the tty and the parser.
This should be called after an error which may have upset the tty's
state.
.It Fn el_gets
Read a line from the tty.
.Fa count
is modified to contain the number of characters read.
Returns the line read if successful, or
.Dv NULL
if no characters were read or if an error occurred.
.It Fn el_getc
Read a character from the tty.
.Fa ch
is modified to contain the character read.
Returns the number of characters read if successful, -1 otherwise.
.It Fn el_push
Pushes
.Fa str
back onto the input stream.
This is used by the macro expansion mechanism.
Refer to the description of
.Ic bind
.Fl s
in
.Xr editrc 5
for more information.
.It Fn el_parse
Parses the
.Fa argv
array (which is
.Fa argc
elements in size)
to execute builtin
.Nm
commands.
If the command is prefixed with
.Dq prog:
then
.Fn el_parse
will only execute the command if
.Dq prog
matches the
.Fa prog
argument supplied to
.Fn el_init .
The return value is
-1 if the command is unknown,
0 if there was no error or
.Dq prog
didn't match, or
1 if the command returned an error.
Refer to
.Xr editrc 5
for more information.
.It Fn el_set
Set
.Nm
parameters.
.Fa op
determines which parameter to set, and each operation has its
own parameter list.
.Pp
The following values for
.Fa op
are supported, along with the required argument list:
.Bl -tag -width 4n
.It Dv EL_PROMPT , Fa "char *(*f)(EditLine *)"
Define prompt printing function as
.Fa f ,
which is to return a string that contains the prompt.
.It Dv EL_RPROMPT , Fa "char *(*f)(EditLine *)"
Define right side prompt printing function as
.Fa f ,
which is to return a string that contains the prompt.
.It Dv EL_TERMINAL , Fa "const char *type"

Set editing mode to
.Fa mode ,
which must be one of
.Dq emacs
or
.Dq vi .
.It Dv EL_SIGNAL , Fa "int flag"

.Nm
will install its own signal handler for the following signals when
reading command input:
.Dv SIGCONT ,
.Dv SIGHUP ,
.Dv SIGINT ,
.Dv SIGQUIT ,
.Dv SIGSTOP ,
.Dv SIGTERM ,
.Dv SIGTSTP ,

.Fn func ,
referred to as
.Fa name
which is invoked when a key which is bound to
.Fa name
is entered.
.Fa help
is a description of
.Fa name .
At invocation time,
.Fa ch
is the key which caused the invocation.
The return value of
.Fn func
should be one of:
.Bl -tag -width "CC_REDISPLAY"

If
.Fa flag
is non-zero,
editing is enabled (the default).
Note that this is only an indication, and does not
affect the operation of
.Nm "" .
At this time, it is the caller's responsibility to
check this
(using
.Fn el_get )
to determine if editing should be enabled or not.
.El
.It Fn el_get

.Sh NAME
.Nm editrc
.Nd configuration file for editline library
.Sh SYNOPSIS
.Nm
.Sh DESCRIPTION
The
.Nm
file defines various settings to be used by the
.Xr editline 3
library.
.Pp
The format of each line is:
.Dl [prog:]command [arg [...]]
.Pp
.Ar command
is one of the
.Xr editline 3
builtin commands.
Refer to
.Sx BUILTIN COMMANDS
for more information.
.Pp
.Ar prog
is the program name string that a program defines when it calls
.Xr el_init 3
to setup
.Xr editline 3 ,
which is usually
.Va argv[0] .
.Ar command
will be executed for any program which matches
.Ar prog .
.Pp
.Ar prog
may also be a
.Xr regex 3
style
regular expression, in which case
.Ar command
will be executed for any program that matches the regular expression.
.Pp
If
.Ar prog
is absent,
.Ar command
is executed for all programs.
.Sh BUILTIN COMMANDS
The
.Nm editline
library has some builtin commands, which affect the way
that the line editing and history functions operate.
These are based on similar named builtins present in the
.Xr tcsh 1
shell.
.Pp
The following builtin commands are available:
.Bl -tag -width 4n
.It Ic bind Xo
.Op Fl a
.Op Fl e
.Op Fl k
.Op Fl l
.Op Fl r
.Op Fl s
.Op Fl v
.Op Ar key Op Ar command
.Xc
Without options, list all bound keys, and the editor command to which
each is bound.
If
.Ar key
is supplied, show the bindings for
.Ar key .
If
.Ar key command
is supplied, bind
.Ar command
to
.Ar key .
Options include:
.Bl -tag -width 4n
.It Fl e
Bind all keys to the standard GNU Emacs-like bindings.
.It Fl v
Bind all keys to the standard
.Xr vi 1 -like
bindings.
.It Fl a
List or change key bindings in the
.Xr vi 1
mode alternate (command mode) key map.
.It Fl k
.Ar key
is interpreted as a symbolic arrow key name, which may be one of
.Sq up ,
.Sq down ,
.Sq left
or
.Sq right .
.It Fl l
List all editor commands and a short description of each.
.It Fl r
Remove a key's binding.
.It Fl s
.Ar command
is taken as a literal string and treated as terminal input when
.Ar key
is typed.
Bound keys in
.Ar command
are themselves reinterpreted, and this continues for ten levels of
interpretation.
.El
.Pp
.Ar command
may be one of the commands documented in
.Sx "EDITOR COMMANDS"
below, or another key.
.Pp
.Ar key
and
.Ar command
can contain control characters of the form
.Sm off
.Sq No ^ Ar character
.Sm on
.Po
e.g.
.Sq ^A
.Pc ,
and the following backslashed escape sequences:
.Pp
.Bl -tag -compact -offset indent -width 4n

Carriage return
.It Ic \et
Horizontal tab
.It Ic \ev
Vertical tab
.Sm off
.It Sy \e Ar nnn
.Sm on
The ASCII character corresponding to the octal number
.Ar nnn .
.El
.Pp
.Sq \e
nullifies the special meaning of the following character,
if it has any, notably
.Sq \e
and
.Sq ^ .
.It Ic echotc Xo
.Op Fl sv
.Ar arg
.Ar ...
.Xc
Exercise terminal capabilities given in
.Ar arg Ar ... .
If
.Ar arg
is
.Sq baud ,
.Sq cols ,
.Sq lines ,
.Sq rows ,
.Sq meta or
.Sq tabs ,
the value of that capability is printed, with
.Dq yes
or
.Dq no
indicating that the terminal does or does not have that capability.
.Pp
.Fl s
returns an emptry string for non-existent capabilities, rather than
causing an error.
.Fl v
causes messages to be verbose.
.It Ic edit Op Li on | Li off
Enable or disable the
.Nm editline
functionality in a program.
.It Ic history
List the history.
.It Ic telltc
List the values of all the terminal capabilities (see
.Xr termcap 5 ).
.It Ic settc Ar cap Ar val
Set the terminal capability
.Ar cap
to
.Ar val ,
as defined in
.Xr termcap 5 .
No sanity checking is done.
.It Ic setty Xo
.Op Fl a
.Op Fl d
.Op Fl q
.Op Fl x
.Op Ar +mode
.Op Ar -mode
.Op Ar mode
.Xc
Control which tty modes that
.Nm
won't allow the user to change.
.Fl d ,
.Fl q
or
.Fl x
tells
.Ic setty
to act on the
.Sq edit ,
.Sq quote
or
.Sq execute
set of tty modes respectively; defaulting to
.Fl x .
.Pp
Without other arguments,
.Ic setty
lists the modes in the chosen set which are fixed on
.Po
.Sq +mode
.Pc
or off
.Po
.Sq -mode
.Pc .
.Fl a
lists all tty modes in the chosen set regardless of the setting.
With
.Ar +mode ,
.Ar -mode
or
.Ar mode ,
fixes
.Ar mode
on or off or removes control of
.Ar mode
in the chosen set.
