I see how it is! :-)  When Shawn says it, it is to be liked.
But when I allude to it a _year_ ago, I'm ignored.

    So, from the git-pull man page:

        For "git push", the local ref that matches <src> is
        used to fast forward the remote ref that matches
        <dst>. If the optional plus + is used, the remote
        ref is updated even if it does not result in a fast
        forward update.

    Ah-ha!  Wait.  But here's the conceptual missing piece:
    When might I _know_ I have the situation where a
    fast-forward update might not happen?  And as a remote
    puller, that would be "never" -- unless I know something
    about the nature of the remote end.  That is, like you
    said, "pu" is subject to wild fluctuation and non-linear
    behavior.  But any random puller can't know that a
    priori.  So far, that is out-of-band information about a
    branch that needs to be "available".

Yep, out-of-band information that needs to be available indeed...

Ah well. :-)
