I've read the patch set twice more now, including reading the patched code.
[That's what weekends are for, right? :-)]
I've got a high level question, and a few nits.
Before I impose submitting another version of the patch I'm hoping
we can get the remaining high level issues resolved first.
I think I better understand the things you have to go through to parse
linespecs, but there's still something here that needs more work.
I think it'll just involve a bit of API tweaking, so nothing major.
I'll leave the discussion to the email with the patch.
Thanks for the effort so far!
Sorry this is taking awhile to review.
