	* plug-ins/jpeg/jpeg-save.[ch]
	* plug-ins/jpeg/jpeg.c: change the behavior of the code so that
	"Use quality settings from original image" does what it claims,
	even if these settings are worse than the user's defaults (note
	that the option is not automatically enabled in this case).  Also
	set the subsampling type when that box is checked.

	* plug-ins/jpeg/jpeg-settings.h: formatting.
