I've been wanting a shortlog script for summarizing my kernel
submissions to Linus for a while. This is now written, and the results
are attached. Simply use like
git-shortlog < changes.txt
or
git-shortlog changes.txt
The changeset format the Perl script parses is that of
http://www.kernel.org/pub/linux/kernel/people/jgarzik/git-changes-script
I'll change it to parse the git-whatchanged output format sometime soon;
Linus hates it when I use git-changes-script since he thinks its ugly :)
