Subject: Make git-find-p4-change only find changes done under perforce.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=f3b6b452d54f2aa5778906efb1c7c6e0267baeeb;p=p5sagit%2Fp5-mst-13.2.git

Make git-find-p4-change only find changes done under perforce.
That way, later cherry-picking that happens to copy the 'p4raw-id:'
text won't be located by mistake.
