Re: [PATCH v2 06/10] grep/pcre2: use compile-time PCREv2 version test

This is not wrong per-se but it does look misleading not to spell it
as

#if (PCRE2_MAJOR == 10 && PCRE2_MINOR >= 36) || PCRE2_MAJOR >= 11

which would convey the intention much clearly.

Hint to notice the difference: imagine if it were "9.37 and later in
9.X series, 10.36 and later in 10.X series and anything after 11 are
OK".

In other words, the minor version is always tied to a particular
major version and "major >= X && minor >= Y" is often a bug, even
though in this case it happens to be OK only because 10 and 11 are
consecutive.
