Many plugins already do this. You may want to look at some of them,
because sometimes the setup rules have been a bit unclear. (Some setup
code expected run_argv_aliases() to be called, which usually doesn't
happen when running from another command). However that might have been
sorted out.

That said, if there isn't an internal api to do the things you want to
do at the Command level, we consider that a bug. The commands should be
just a command-line glue to get you into domain objects (Branch, etc).

I'll also note that Command level interaction means re-opening branches,
etc, and I don't think that will allow connections to be held open. So
you may end up with multiple ssh handshakes.

Short answer: yes you can do it, but we'd like to know why you want/need to.
