Do you think the glib regex maintainers would be amenable to adding 1)
external iterator support (that we'd use to deal with the gap), and 2)
user-pluggable callouts (which we'd use to implement Emacs-specific
assertions)? I'd rather not have a huge pile of ifdefs the way we do now.
I'd much prefer using maintained extension points.
