Well, guess what!  It turns out my patch was just fine.  It turns out
what you need to do is:

  autossh -M 0 fencepost.gnu.org

It appears Debian must have applied a patch (I haven't verified this)
that makes "-M 0" the default.  Otherwise this works just fine.

I've actually been using it for a while but forgot to contribute it.

Here's the updated patch!  If people are ok with it, I'd like to push
it.
