As to the question of whether the committer was the 'script' or the wiki editor... I'm not sure. Marking it as the script somehow (`ikiwiki-cgi <ikiwiki@sitename>`)? seems to make sense and would make it easier to manage.

+I've been thinking a bit about the GIT attribution in ikiwiki...
+
+If no email set, I think "$USERNAME" is reasonable... no point in the
+'<>' causing clutter.
+>> **adjustement wrt comments**: leave the '<>' in due to requirements in git
+
+If no username set... then something like '@[IPADDR]' makes sense...
+(not in email brackets).
+

+
+In the case of OpenID login.. I think that's a special case... I don't
+think attempting to munge something meaningful out of the OpenID makes
+sense... but I think some massaging might need to be done.
+
+Ex: I've noticed in the current mode where logging in w/
+harningt.eharning.us/ shows up in the logs w/o HTTP and if I login w/
+http://harningt.eharning.us/ is shows up w/ the http... causing some
+inconsistency. I think it oughtta make sure that it has the properly
+discovered, canonicalized form (ex: if there's a redirect to another
+site (harningt.eharning.us -> www.eharning.us) then technically the
+target site is the 'real' openid (at least according to how most OpenID
+RPs take it).
+
+...
+
+For OpenID edits, I think there should be a way to tell it what
+username to show in the preferences dialog (so you can have a 'normal'
+$USER <$EMAIL> setup.) This could by default be filled in w/ sreg
+nickname value (as well as email for that matter)...
+
+To convey the openid used to make the edit, I think it would be
+important that some sort of footer line along the lines of the
+Signed-off: $USER <$EMAIL> conventions I've seen.
+
+Perhaps an OpenID: $OPENID_URL would make sense. This could help w/
+making sure that no one irrefutably spoofs a post by someone (since w/
+the setup where email and effective username are configurable, there's
+no determination of uniqueness)
+>> **adj re git req**: "$OPENID_URL <>"

+
+[[madduck]]: git requires `Name <Email@address>` format, as far as I know.

+> fatal: malformed --author parameter
+>
+> It seems to be happy with anything of the form "foo <foo>" -- doesn't seem to
