[PATCH] Parse and use header data from an hg export'ed changeset
From: Andrew Thompson <andrewkt@aktzero.com>
This should make it easier to import changesets that are hg export'ed
from other Mercurial users:
Add a routine to catch the user from an hg export'ed changeset.
Add user to commit call.
Add trap for changelog snippet, which is promoted to the beginning of
the commit text.
