push: return 1 if no changes found (issue3228)

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       0

This fixes the lower-right entry.
