Hello,
 I would like to submit my first patch to the git community.

I have introduced a new configuration option to 'git-p4' "kwstrip". If enabled, the RCS keywords gets unexpanded like it is done with out the patch and disabling it explicitly retains the RCS keywords as in the original p4 source. The default (in the absence) is 'false' to ensure backward compatibility. To override, you can put the following lines in your '.gitconfig' file..

[git-p4]
        kwstrip = false



The patch to git-p4 (based on origin/next branch):
