No. As it stands, the PCRE content in config.nmake and Makefile.nmake
add unnecessary clutter.

Would it be better to deprive users of functionality so the code can be
pretty?

You're assuming that there's a version of PCRE available to restore.
This isn't the case on 64-bit Windows, which is what prompted the move
to GRegex in the first place. GRegex lets us have more uniform feature
parity across the different platforms we support and removes a
dependency on an external library. However, it isn't available in older
versions of GLib so the pre-existing PCRE code has been left in place.

At some point we'll probably abandon PCRE entirely in favor of GRegex,
particularly if we require 2.14 or later.
