Subject: Shipping gitk as part of core git.

It appears that gitk gets wider test coverage only after it is
pulled into git.git repository.  I think it would be a good idea
for me to pull from you often.

Recently there was a discussion with binary packaging folks.
While I do not mind, and actually I would prefer, shipping gitk
as part of the core GIT, I have never heard about your
preference.  As long as gitk is just a single file (or even a
handful files in the future) project that does not have a
filename that overlaps with core GIT, I can continue pulling
from you and I think the binary packaging folks can produce
separate git-core and gitk package out of git.git tree without
problems.  However, once you start wanting to have your own
Makefile and maybe debian/rules file for packaging, for example,
I suspect the way currently things are set up would break
miserably.  It's all Linus' fault to have merged with your tree
in the first place ;-).

Anyhow, I have one bug to report.  I selected one rev, and then
said "diff this -> selected" from right-click menu on an
adjacent one, and I got this:

    wrong # args: should be "startdiff ids"
    wrong # args: should be "startdiff ids"
        while executing
    "startdiff $newid [list $oldid]"
        (procedure "diffvssel" line 28)
        invoked from within
    "diffvssel 0"
        invoked from within
    ".rowctxmenu invoke active"
        ("uplevel" body line 1)
        invoked from within
    "uplevel #0 [list $w invoke active]"
        (procedure "tk::MenuInvoke" line 47)
        invoked from within
    "tk::MenuInvoke .rowctxmenu 1"
        (command bound to event)

The following seems to fix it.
------------
Fix diff invoked from the right-click menu.
