It's possible to have it only run if a specific branch is updated (make
note of that from note_netsync_revision_received). I don't think you can
make it select by db, but that only matters if you have the same branch
in several dbs.

You'd also probably want to check for multiple heads, which would make
the update fail, and maybe check for uncommitted work that could
potentially be garbled by a failed update merge.

I'm not sure you can, and if you can I'm not sure that things would work
as expected (monotone probably wouldn't like suddenly finding itself
somewhere it didn't think it was).

Really, that'd be a good place for the --working-directory (should
probably actually be --workspace) parameter you suggested.
