A quick search found the following message by Dirkjan, but it is likely
earlier messages on the subject had been posted too:
http://mail.python.org/pipermail/python-dev/2009-July/090325.html

By the way, the "pymigr" repository where the "all-branches.txt" file is
stored is now only accessible through the ssh:// URLs, as someone
complained that unmangled e-mail addresses of former committers were
given out by the Web UI (in the "author-map" file).

Regardless, since Alexander's previous work was in the sandbox repo (not
the python repo), I don't think it would have been possible to integrate
it during the hg migration.

Antoine.
