[patch] prefer "git COMMAND" over "git-COMMAND" in gitk

Preferring git _space_ COMMAND over git _dash_ COMMAND allows the
user to have only git and gitk in their path. e.g. when git and gitk
are symbolic links in a personal bin directory to the real git and gitk.

Perfect time to say Thanks for the great work.

Thanks for the patch.  It was whitespace-damaged but I fixed it up
(this once) and applied it.  Also, if you send any larger patches in
future I'd like a Signed-off-by line with them (this one was trivial
enough that I applied it without).

Paul.
