[PATCH] contrib: pick: tidy up pick-format-field

Previously this function used a temporary variable to store the return
value but we can just use the return value of the cond statement
directly.

The only tiny subtlety is that in one case (subject) we need to
slightly reorder the logic to make sure the formatted-field is the
last thing computed.

This follows Tomi's suggestion in id:m2ob7vg24n.fsf@guru.guru-group.fi                                                                                     and simplifies the code here slightly. This patch applies on top of                                                                                        the series at                                                                                                                                              id:1378092488-32050-1-git-send-email-markwalters1009@gmail.com                                                                                             

(It also includes one small whitespace fix-up for the face for the tags)
