ALTER TABLE DISABLE KEYS doesn't work when modifying the table
  
ENABLE|DISABLE KEYS combined with another ALTER TABLE option, different
than RENAME TO did nothing. Also, if the table had disabled keys
and was ALTER-ed then the end table was with enabled keys.
  
Fixed by checking whether the table had disabled keys and enabling them
in the copied table.

Installing libc6-dbg on Debian will still provide proper bactraces, even
without setting LD_LIBRARY_PATH explicitly.

There was an improper order of doing chained operations.

To the documentor: ENABLE|DISABLE KEYS combined with RENAME TO, and no other
ALTER TABLE clause, leads to server crash independent of the presence of
indices and data in the table.

	with embedded spaces
  
Problem:  Original code written assuming password contains no spaces.
Further, because of how sh interprets characters in variables, you
cannot do the "simple solution".
  
Solution:  Move the "was a password provided" check to the end. This
allows us to correctly quote the password argument when passed to the
mysql client program.  Addendum:  Put this check inside of a shell fn
to simplify the code.
