tail --follow=name no longer implies --retry

* src/tail.c (tail_forever_inotify): Just as without inotify,
tail --follow=name now terminates when the last tailed-by-name file
is unlinked or moved aside.  This bug was introduced on 2009-06-15
via commit ae494d4b, "tail: use inotify if it is available".

* NEWS (Bug fixes): Mention this.
* tests/tail-2/follow-name: Test for this.
* tests/Makefile.am (TESTS): Add it.
