  I'm happy with this feature.
  
  But the code needs work around multiple revisions/heads before it can be 
queued.

What happens if we're pushing multiple heads? I suspect this will choose a 
head/revision arbitrarily - maybe depending on the `-r` arguments to `hg push`.

I think we need to validate that the outgoing revs are in a single DAG head and 
we should then pick the rev that is the DAG head.

Please add test coverage for multiple `-r` arguments and `-r` arguments that 
resolve to multiple heads.

Nit: what is `--create`?

Strictly speaking, we should probably wrap `exchange._pushdiscoverybookmarks` 
so other extensions can get involved. But I think this is fine.
