I'm aware of it. I just didn't remember it when I wrote this code.

And if I remember correctly Mike Haggerty had a series to refactor ref
parsing code and reuse in this place (it was my promise to do it, but
he took over). I think the series was halted because refs.c was going
through a major update at that time. I think we could leave it as is
for now and completely replace it at some point in future.
