To clarify, I'm not advocating any such demotion of PCRE.  However,
*IF* the presence of the option when the module is not available is
really a serious problem, then I think the right thing is to remove
the option, rather than to expand the special case.

It's the recent "zregexparse" thread where this came up.  I'm not sure
there is anything to be done about it; the zsh/regex module would have
to become part of the default static build, which might have licensing
consequences.
