[PATCH] A couple of driver cleanups

[Nathan Sidwell]

I'm applying this obvious patch.  Two hunks deal with inappropriate line 
breaks, and the first changes the baroque:
    var = (thing) ? thing : var;
into the much clearer
    if (thing)
      var = thing;

	gcc.c
	* (execute): Simplify cond-expr into if.  Reformat command.
	(run_attempt): Reformat line break.
