	* src/files (compute_exts_from_gf, compute_exts_from_src): Handle
	the case where header_extension is the same as src_extension, aka
	handle -d -o <file> where <file> doesn't have a known EXT to
	transform. e.g. if <file> is <something>.yxx, set the
	header_extension to <something>.yxx.h, as would do bison 1.28.
