Colin Percival f9f231846a Don't try to mmap the contents of empty files. This behaviour was harmless ... prior to r195693, since historical behaviour of mmap(2) was to silently ignore length-zero mmap requests; but mmap now returns EINVAL, which caused look(1) to emit an error message and fail. Among other things, this makes `freebsd-update fetch` on a newly installed 8.0-BETA3 system print bogus warning messages. MFC after: 3 days		2009-08-26 03:30:06 +00:00
