[PATCH 5/6] git-p4: keyword flattening fixes

[Pete Wyckoff <pw@padd.com>]

Join the text before looking for keywords.  There is nothing to
prevent the p4 output marshaller from splitting in the middle of a
keyword, although it has never been known to happen.

Also remove the (?i) regexp modifier; perforce keywords are
documented as case-sensitive.

Remove the "\n" end-character match.  I don't know why that is
in there, and every keyword in a fairly large production p4 repository
always ends with a $.
