Yeah, I like it a lot. Nice work.

Any idea, what's the reason, it doesn't find anything here in the
kernel tree:
  git-rev-list HEAD | git-diff-tree -S'TIMEOUT' --stdin

while:
  git-rev-list --header HEAD | grep -z TIMEOUT

prints the commit:
  6897089c5f7989603ccb9c696050470ba1dbd262

with the following change:

Nice feature, maybe we can add it later (see next).

I see what you mean, but allow to pass any charater through a cgi to a invoked shell as a command-line option is a nightmare without being very carful. That's why only a few character allowed now. I'm not sure how to do that without creating possibly a big hole in the webserver. :)
