* grep: fix -F crash when alternating duplicatesNorihiro Tanaka2016-07-141-0/+24
grep -F crashes with a pattern like 0\n0. This bug was introduced in 966f6586fbce3081ce6e5e2f9b55301b0ec3d2b4. * src/kwset.c (memoff2_kwset): If two characters are the same, use memchr instead of memchr2. * tests/two-chars: New test. * tests/Makefile.am (TESTS): Add it.
