grep: fix --devices=ACTION (-D) so stdin is once again exempt
An oversight in the 2.11 changes made it so "echo x|grep x" would
fail for those who set GREP_OPTIONS=--devices=skip.
* src/main.c (grepdesc): Ignore skip-related options when reading
from standard input.
* tests/skip-device: New file. Test for the above.
* tests/Makefile.am (TESTS): Add it.
* doc/grep.texi (File and Directory Selection): Clarify this point,
documenting the stdin exemption.
* NEWS (Bug fixes): Mention it, and add a few "[fixed in ...] notes.
Reported by Tino Keitel in http://bugs.debian.org/669084,
