fixup! push: support pushing to a remote group

* Do not lose the blank between functions.

* remote_group.nr is of size_t, so the compiler will complain about
  this comparison that stops a platform natural integer approaching
  the limit from below for type and signedness mismatch, even though
  it would be insane to try defining a remote group whose size would
  not fit platform natural integer.
