[PATCH/RFC v4] git-p4: warn if git authorship won't be retained

[Luke Diamand <luke@diamand.org>]

Updated version of git-p4 authorship warning suggested by Junio,
incorporating fixes for problems in v2 pointed out by Peter Wyckoff.

In the previous version of this patch I forgot to add an && in the
test harness.

Pete suggested doing "grep -q" however it turns out that this
doesn't work - git-p4 explodes when it tries to do stdout.flush() at
line 1588 in importChanges(). I can only imagine that grep -q does
something very subtle to stdin.
