treediscovery: always return all remote heads Old discovery only returned incoming heads, not all of them (for changegroupsubset). New discovery must always return all of the remote heads (for getbundle). I failed to properly adjust treediscovery in cb98fed52495 when introducing setdiscovery. The actual observable problem was 'remote: unsynced changes' when trying to push a cset on one named branch to a server with a new cset on another named branch. This scenario is now tested in test-treediscovery.t.

'''share a common history between several working directories'''

def share(ui, source, dest=None, noupdate=False):
    """create a new shared repository

    Initialize a new repository and working directory that shares its
    history with another repository.

    .. note::
       using rollback or extensions that destroy/modify history (mq,
       rebase, etc.) can cause considerable confusion with shared
       clones. In particular, if two shared clones are both updated to
       the same changeset, and one of them destroys that changeset
       with rollback, the other clone will suddenly stop working: all
       operations will fail with "abort: working directory has unknown
       parent". The only known workaround is to use debugsetparents on
       the broken clone to reset it to a changeset that still exists
       (e.g. tip).
