Yes, you get an email notifying you of the branch being deleted,
and what commit the branch was pointing to before the removal
of that branch. In addition, if any commits are "lost" (no longer
accessible from any remaining branch or other reference), then
a list of the commits that are no longer on any branch is included
as well.

Here is an example of what you'd get in the simple case:

| From: Test Suite <testsuite@adacore.com>
| To: git-hooks-ci@example.com
| Subject: [repo] Deleted branch old-branch
| X-Act-Checkin: repo
| X-Git-Author: Test Suite <testsuite@adacore.com>
| X-Git-Refname: refs/heads/old-branch
| X-Git-Oldrev: cc8d2c2637bda27f0bc2125181dd2f8534d16222
| X-Git-Newrev: 0000000000000000000000000000000000000000
|
| The branch 'old-branch' was deleted.
| It previously pointed to:
|
|  cc8d2c2... Modify `c', delete `b'.

No such option is available at the moment.

Personally, I wouldn't like having a URL, at least not instead
of a diff.  I think having a diff is much more useful and immediate,
as I use those as a chance to review post commit as well, or verify
that what's committed is what was discussed on the list.

But for large commits, there is a limit to the maximum size of
the email, after which the email is truncated.
