prepush: print short hash of first new head in abort message and don't mention the branch if it's the default branch. OLD: $ hg push ../a pushing to ../a searching for changes abort: push creates new remote heads on branch 'default'! (you should pull and merge or use push -f to force) NEW: $ hg push ../a pushing to ../a searching for changes abort: push creates new remote head 1e108cc5548c! (you should pull and merge or use push -f to force) This helps to identify which local head is causing troubles. See also change 91cb08a9e7fb.

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

    """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).
