Cool -- glad to know this passes another person's sanity filter.

Fortunately, that's not commit-email.pl's job. It can assume that the
caller can construct the URL, no matter how complex a job that is.
(Because the alternative is for commit-email.pl to do it, and if
commit-email.pl can do it, so could its caller -- they're both just
programs, right?).

We don't need to modify post-commit.tmpl, though we could. It's just
an example. People do all sorts of weird, complex things in their
hook scripts, things that have never been included in the .tmpl files.

Hint: stop thinking about the post-commit template script :-). It's
irrelevant to this issue.
The point is to give commit-email.pl the ability to use a certain
piece of information that will be passed to it verbatim. Coming up
with that information is someone else's job (we know it can be done,
of course, but actually doing it is not part of this change).
