This patch changes string_from_display_spec (a static function in
xdisp.c) to use a do while loop instead of a while loop.  The
precondition is checked by the if statement and is redundant in the
first iteration.  This redundancy is now removed.

The indenting for 'do-while' wasn't using the usual GNU style, and while fixing that I noticed that the code could be further simplified, so I installed the attached further patch.
