When run with the Git backend, ikiwiki should use GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL rather than munging the commit message. Depending on the semantics you want to imply (does a web edit constitute a commit by the user or by the script?), it could also set GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL to the same values. --JoshTriplett
