Re: inconsistency links and code line labels

I should have mentioned that I'm not exporting any of this. I only use org
by itself; I never export things to other formats. So the link behavior
that I need is for making and following links inside org/emacs; noweb and
other things aren't important.

The (ahem) link to the org-coderef-label-format is what I was looking for:
I set that to just (%s) and now something like the above example works
without adding the "ref:" bit. I'll update the emacs.sx post.

Thanks!
