One issue with a pre-hook is that is avertable. A second issue is that is 
not enforceable per project as it only applies to the repository where it 
is configured in prefs (or at most to a user if in defaults).

My idea, is that if someone chooses to impose some style rules in patch 
naming in a project, one wants to enforce them amongst all developers 
participating in that project. I see this as a project wide style policy 
and I do not want a user to ignore it. Even more, I do not want the user 
to be forced to go back and amend all his ill named patches because 
otherwise he cannot push them to a repo with a pre-hook. I would want him 
to see this as soon as possible, when he records. Imagine some third 
party trying to contribute to your project. Gets the repo, records some 
changes and then sends over email. I will have to write back just to say 
they need to be renamed, because he never sees my pre-hooks and is 
unaware of the style policy.

My idea with setpref is that it can propagate between sibling 
repositories, much like a boring file setting, unlike any hook.
