stat: interpret "-" as standard input
* src/stat.c (do_stat): Interpret a command line argument of "-" to mean "standard input", like many other tools do. (do_statfs): Fail upon any attempt to use "-". * NEWS (Changes in behavior): Mention it. * tests/misc/stat-hyphen: New test, to exercise the above. * tests/Makefile.am (TESTS): Add misc/stat-hyphen.
