tail -f: handle "-"/stdin once again
* src/tail.c (main) [HAVE_INOTIFY]: When stdin (i.e., "-", or no args,
but not /dev/stdin) is specified on the command line, don't use inotify.
Reported by Bill Brelsford in <http://bugs.debian.org/545422>.
* tests/tail-2/follow-stdin: New file. Test for this.
* tests/Makefile.am (TESTS): Add the test.
* NEWS (Bug fixes): Mention it.
This bug was introduced in coreutils-7.5 via commit ae494d4b,
2009-06-02, "tail: use inotify if it is available".
