One thing though, I didn't put the ChangeLog diffs in the patch as I usually add them when committing.
Oh, I missed that. I added them now. For Gnulib it's better to put them into the patch.
It is no longer possible to shrink an obstack with obstack_blank (but you can still do that with obstack_blank_fast).
Ouch, I hadn't noticed that. That's an incompatible change and I expect it will break real-world usage for no particularly good reason, so we really need to fix this. How about making the 2nd argument to obstack_blank and obstack_blank_fast be of type ptrdiff_t rather than size_t?
