Grepping through the source I see several places that can be simplified
by converting them to strchrnul(), so I think introducing this GNU
extension is a good idea in any case.

Using strchr()/strchrnul() instead of strbuf_addch()'ing is sensible, of
course.  I don't like the duplicate code in your sketch above, though.
I'll try to look into it later today.

Thanks!
