Change the revprop as part of the process. (Ryan has
already detailed how on this thread.)

We're on Windows, so the exact mechanism is not cron,
but that's precisely the idea. We extract some of the
commit data using svnlook in a post-commit into an
MS-SQL DB, as well as writing marker files for non-DB
enabled apps. Then other processes either poll the DB,
wake up via scheduled tasks (windows ~crontab), or use
the marker files for synchronization.

You can edit the revision history so that's the case
(for all but a fraction of a second). Ryan has the
recipe on thread.

Then use two commits, and the second commit mail will
automatically do this. You'll have to check on the
timing with the revprop change for what user
svnnotify will say made the change. If that tool is
synchronous in a post-commit hook, it may report the
shared user as the committer still. (In this case,
change the committer revprop in the post-commit hook
of the second commit, parsing the "real" user out of
the commit string or something, before running
svnnotify.) I'm not familiar with that tool.
