For Andrew or anyone else that knows, can we assume

smart enough that if the first part of an AND clause fails then the
other parts don't run (or similarly if the first part of an OR
succeeds)? If so, we can probably optimize rules by doing easy checks
first before complex ones.
No, everything will be evaluated.
Note that the problem with rule 48 was that added_links triggers a
complete parse of the pre-edit page text. It could be replaced by a
check against the externallinks table. No amount of clever shortcut
evaluation would have made it fast.
