pull: return 1 when no changes found (BC)
Currently we have the following return codes if nothing is found:
commit incoming outgoing pull push
intended 1 1 1 1 1
documented 1 1 1 0 1
actual 1 1 1 0 1
This makes pull agree with the rest of the table and makes it easy to
detect "nothing was pulled" in scripts.
