The notify extension does include file-pattern matching support, so you
can add for example:

    # Commit-mail subscriptions.
    [usersubs]
    userA at example.org = some/path/test.txt
    userB at example.org = some/other/path/test.txt
    mailing-list at example.org = **

Updating the `.hg/hgrc' file of the repository when users change their mind
is going to be slightly more complex, as you would have to install some
sort of hook that updates it externally.

For instance, you can add a toplevel hgadmin/ directory in the repository
itself and add a version tracked file called `hgadmin/commit-mail.conf'.
Then you can install a push hook on the main repository that tracks commits
to that file and updates `.hg/hgrc' in place.

This way interested committers can register their interest to any file
pattern they like by committing to `hgadmin/commit-mail.conf', you get
tracking of who changed the file, when it was changed, by whom, etc.
