Checking prepush logic does not allow silently pushing 
multiple new heads:

Check prepush logic with merged branches:

  $ hg -R j ci -Am init

  $ hg clone j k
  updating to branch a

  $ hg -R k ci -m merge

  $ hg -R k push -r a j

  abort: push creates new remote branches: b!

Prepush -r should not allow you to sneak in new heads:

  $ hg -q up null

  $ hg -q merge b
  $ hg -q ci -mmb
  $ hg -q up 0
  $ echo a >> foo
  $ hg -q ci -ma2
  $ hg -q up 2
  $ echo a >> foo
  $ hg -q branch -f b
  $ hg -q ci -mb2
  $ hg -q merge 3
