[PATCH 2/2] send-pack: print "maybe you need to pull" hint

If there were refs rejected for not being fastforwards, then
we used to print a "maybe you are not up-to-date" hint. This
was lost in the recent terse-output patches.

I am slightly negative on this patch, just because I always found that
particular warning a bit ugly (and the new output is so nice and
compact). But for new users, perhaps the extra hint is helpful?

If we do want the warning, then other options include:
  - listing each non-fast forward, as Alex's original patch did; this
    seems kind of pointless given that they are clustered at the bottom
    already
  - possibly cluster non-fast forwards differently from other errors in
    the output
  - tweak the text
