OK thanks. If it's hard, fair enough, leave it for now.

| Well, the problem with the old implementation of the ticket updater is
| that it's an external Python script calling into the Trac python API and
| messing around with Trac's sqlite database via SQL commands
| directly. This was the common ad-hoc way to do this kind of things up to
| Trac 0.11, but starting with Trac 0.12 a proper facility was provided[1]
| which is better integrated with Trac and what most people (who didn't
| give up on Trac) use nowadays.
| 
| So going back to the old script is not recommended. Otoh, it's possible
| to extend by sub-classing the standard CommitTicketUpdater[1] component,
| and trying to re-create the information provided by the previous
| hook-script in a more "modern" way. However, if it's not high-priority
| I'd like to postpone tackling this until after GHC 7.8 is released.
