A node spans multiple lines if the line difference
between start and end point is > 0 (rather than > 1).
Fixes some odd cases introduced by CL 5706055;
pointed out by dsymonds.

Added corresponding test case. The other change
in the .golden file reverts to the status before
the CL mentioned above and is correct.

gofmt -w src misc changes godoc.go back to where
it was before the CL mentioned above.

Fixes #3304.

1) Poor error checking in variable declarations admitted
$x=2 or even $x%2.
2) Need white space or suitable termination character
after identifiers, so $x+2 doesn't parse, in case we want it
to mean something one day.
Number 2 in particular prevents mistakes that we will have
to honor later and so is necessary for Go 1.

Fixes #3270.

Windows has paths like C:/Users/ADMIN~1. Also, it so happens
that go/parser allows ~ in import paths. So does the spec.

This should live in archive/tar later (CL 5796073) but we
can always do that after Go 1 and stick it here for now.

This makes h3 and h4 more distinct, and h2 and h3 the same size.
The h2 and h3 styles may be distinguished h2's background styles.

This means that almost all text on the site is either 16px, 20px,
or 24px. (with a smattering of 14px)

I did not put any go file in doc/progs. Shoul I include Go files
with those declarations?

For URLs ending with /, the handler did not work, trying to append
".xml" to the path.

For instance, the "Share Memory by Communicating" returned the
following error:

        open /Users/francisco.souza/lib/go/doc/codewalk/sharemem/.xml: no such file or directory

««« original CL description
cmd/go: respect $GOBIN always

Before, we only consulted $GOBIN for source code
found in $GOROOT, but that's confusing to explain
and less useful.  The new behavior lets users set
GOBIN=$HOME/bin and have all go-compiled binaries
installed there.

Fixes #3269.
