tests: don't overwrite HGRCPATH Overwriting instead of appending to the file removes the [defaults] section put into the file by run-tests.py. It also defeats the --inotify option to run-tests.py. (Nothing was broken yet, but the lack of -d "0 0" cause changeset hashes to change unexpectedly in a test case I was editing.)

'''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).
