This patch adds -C (change working directory) parameter to
gitk. With this parameter, instead of need to cd to directory
with .git folder, one can point the correct folder from
commandline.
v2: Adjusted the parameter as per Eric's suggestion. I think
it now work in similar manner as in many GNU tools as well
as git itself.
