Thanks.

BTW, I was wrong about

  static char const xprefix[] = "^(?:";
  static char const xsuffix[] = ")$";

(as opposed to \A, \z) causing a problem with grep -Pxz '(?m)...'

as the pattern becomes ^(?:(?m)...)$, so the m flag is only
applied within the (?:...). I can see pcre_compile() supports a
PCRE_ANCHORED flag, but it looks like it only makes ^ implicit
(not $).
