That's OK, if you prefer a source-to-source transformation then you can
use that instead, but the point is that this should be done for all uses
of the regexp code, not just for some of them.
The Emacs regexp code isn't Perl-inspired, as far as I know. It's an
old copy of the glibc code, with a lot of hacks. The glibc version
mutated quite a bit when it added i18n support, and Emacs's version has
mutated in different ways.
