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.
