This can already be done by setting

subject_updates_title = no
in the [mailgw] section of config.ini

This, of course, prevents *all* title updates via the subject. I've
generally found that turning this off in production trackers is a good
idea with all the subject mangling going on with diverse mail clients.

You can still set the title explicitly via email by appending
[title=new title] to the subject :-)
