From what I understand so far there is something preventing this as the
file to be formatted does not 'exist' on the server until after the

Right, this is the second problem. Even if the post commit file contents
could be modified, those modifications could not be sent back to the
client using the existing protocol.

I think this feature is certainly better than dubious. As far as the
most sane way to implement, I feel that a server side implementation,
even if difficult, is more sane that implementing the feature in every
client application ever created.
