Subject: Bring Porting/checkAUTHORS.pl into the world of git.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=5a52808733f845692a150e91007cb58ebf12ac48;p=p5sagit%2Fp5-mst-13.2.git

Bring Porting/checkAUTHORS.pl into the world of git.

Now processes git log output rather than the Changes file.  E.g.,

% git log --pretty=fuller --name-status perl-5.10.0..HEAD \
? | perl Porting/checkAUTHORS.pl --rank --percentage -

Also, the meaning of --thanks-applied has changed; it now only counts
commits where the committer is not the author.
