Other GUI tools may occasionally need to start
gitk and make it automatically select a certain
commit. This patch supports doing it through the
environment or command line.
Using the environment allows graceful degradation of
the tool when used with an old version of gitk:
unsupported command line options cause it to die.

I decided to send it now.
