 I was suprised to receive two mails from ikiwiki about one web edit:

 But the second had a diff for modifications I made to ikiwiki code
 around the same time (2a6e353c205a6c2c8b8e2eaf85fe9c585c1af0cd).

 Ikiwiki's own locking prevents this from happenning if both commits are web

+A related problem is that if two commits are made separately but then
+pushed in together, the commit code only looks at the HEAD commit, which
+is the second one. No notification is sent for the first.

+Based on all of these problems with using the post-update hook, ikiwiki
+should be changed to use the post-receive hook, which provides enough
+information to avoid the assumuptions that led to these problems.
+Transitioning existing wikis to using a new hook will be interesting. Also,
+this hook is only present in git >= 1.5.0.7.
