I don't understand how these two consecutive patches works.  Assume I don't have "convert". Before the patches Emacs would complain, and installing ImageMagick would fix the complaint.  After, Emacs will complain about not finding "convert", but after I install ImageMagick Emacs will keep complaining, because the defcustom will still be nil.  Is this intended?  Or am I misunderstanding something?
