fetch: added support for named branches

Previously, fetch didn't really work when there were multiple named branches
in the repository. Now it tries to do the right thing(tm) in all situations.

#!/bin/sh

# adjust to non-default HGPORT, e.g. with run-tests.py -j
hideport() { sed "s/localhost:$HGPORT/localhost:20059/"; }
hidehash() { sed "s/changeset 3:............ merges/changeset 3:... merges/"; }

echo "fetch=" >> $HGRCPATH

# repo, because the path of the repo will be included in the commit
# message, making every commit appear different.
