[RFC/PATCH 2/2] builtin-merge: show user-friendly error messages for fast-forward too.

[Matthieu Moy <Matthieu.Moy@imag.fr>]

fadd069d03 (merge-recursive: give less scary messages when merge did not
start, Sep 7 2009) introduced some friendlier error message for merge
failure, but the messages were shown only for non-fast forward merges.
This patch uses the same for fast-forward.

This is where I'm not 100% sure I'm not breaking some plumbing.
