grep -F: avoid an infinite loop with invalid multi-byte search string
* src/kwsearch.c (Fexecute): Avoid an infinite loop when processing
a fixed (-F) multibyte search string that is an invalid byte sequence
in the current locale and that matches the bytes of the input twice
on a line. Reported by Daisuke GOTO in
http://thread.gmane.org/gmane.comp.gnu.grep.bugs/4773
* tests/invalid-multibyte-infloop: New test.
* tests/Makefile.am (TESTS): Add it.
* NEWS (Bug fixes): Mention it.
