[PATCHv4 1/2] git-p4: add test case for RCS keywords

[Luke Diamand <luke@diamand.org>]

RCS keywords cause problems for git-p4 as perforce always
expands them (if +k is set) and so when applying the patch,
git reports that the files have been modified by both sides,
when in fact they haven't.

This adds a failing test case to demonstrate the problem.
