[PATCH] zless: support compressed stdin

Re: [PATCH] zless: support compressed stdin

Thanks, I fixed that in a slightly different way, something more portable to ancient shells. zless: decompress stdin too, if less 429 or later * zless.in: Use LESSOPEN |- feature of less 429 or later. Problem reported by Jeroen Roovers via Mike Frysinger in
