[Python-apps-team] Bug#569554: #569554: patch

Hello,

Patch attached. But recent Mercurial versions will by
default fail for interactive commits if a username
isn't configured, so this change may not be that useful.

This is already supported: just set HGUSER (see "hg help
environment" for details). Alternatively you may set
your username in ~/.hgrc, like this:

[ui]
username = rjc at coker.com.au

Regards,
Wagner
