That's what the "changelogs" feature in reposurgeon does, when the commit that made the change also added a ChangeLog entry. In the case where the commit didn't add a ChangeLog entry, a name and email address from an author map is the best we can practically do (and I think it's much better than having something that never was a valid name and email address for author or committer at all). In particular, that applies to changes from the gcc2 tree (where ChangeLog wasn't version controlled at all until 1998, and after that didn't generally have log messages that could be matched up with those of the corresponding commits to other files). Many of the names and addresses in the author map for the gcc2 repository *are* taken directly from the ChangeLogs (for some commit for each committer) as that was the most practical way of identifying who all the committers from that period were. -- Joseph S.
