Re: [PATCH 2/2] grep/pcre2: factor out literal variable

Aside: Not needed for this change, but I wonder if we could benefit minutely
from:

    #ifdef PCRE2_LITERAL
    options |= PCRE2_LITERAL;
    #endif

It'll save PCRE2 the small effort of finding that we've got no metacharacters.

After the dust settles, it would be a good addition in a separate
patch.

Thanks.
