Don't strip leading slashes for perforce diffs.
Review Request #5879 — Created May 26, 2014 and submitted
Because perforce depot paths start with //, stripping a leading slash is a bad,
bad thing. I've moved the filename normalization into the diff parser, and
overridden it in the perforce specialization.
Ran unit tests.
