As discussed in the last commit partially fix a bug introduced in
b65abcafc7 ("grep: use PCRE v2 for optimized fixed-string search",
2019-07-01). Because PCRE v2, unlike kwset, validates its UTF-8 input
we'd die on e.g.:
fatal: pcre2_match failed with error code -22: UTF-8 error:
isolated byte with 0x80 bit set
When grepping a non-ASCII fixed string. This is a more general problem
that's hard to fix, but we can at least fix the most common case of
grepping for a fixed string without "-i". I can't think of a reason
for why we'd turn on PCRE2_UTF when matching byte-for-byte like that.
