transplant: clarify what --branch do - it has nothing to do with branches

--branch specifies heads and has nothing to do with named branches, and it only
deals with topological branches to the same extent as all other DAG operations
do.

    You can rewrite the changelog message with the --filter option.
    Its argument will be invoked with the current changelog message as
    $1 and the patch as $2.

    If --source/-s is specified, selects changesets from the named
    repository. If --branch/-b is specified, selects changesets from
    the branch holding the named revision, up to that revision. If
    --all/-a is specified, all changesets on the branch will be
    transplanted, otherwise you will be prompted to select the
    changesets you want.

    :hg:`transplant --branch REV --all` will transplant the
    selected branch (up to the named revision) onto your current
    working directory.

    You can optionally mark selected transplanted changesets as merge
    changesets. You will not be prompted to transplant any ancestors
    of a merged transplant, and you can merge descendants of them
    normally instead of transplanting them.

    If --source/-s is specified, selects changesets from the named

    If --branch/-b is specified, these revisions will be used as
    heads when deciding which changsets to transplant, just as if only
    these revisions had been pulled.
    If --all/-a is specified, all the revisions up to the heads specified
    with --branch will be transplanted.

    Example:

    - transplant all changes up to REV on top of your current revision::

        hg transplant --branch REV --all

    You can optionally mark selected transplanted changesets as merge
    changesets. You will not be prompted to transplant any ancestors
