This is v2 of a patch series to implement iteration over references via iterators. Thanks to Ramsay, Eric, Junio, and David for their feedback about v1 [1]. I think I have addressed all of the points that were raised. Changes from v1 -> v2: * In "refs: introduce an iterator interface": * Fix some comments. * Remove a redundant call to `sort_ref_dir()`. * Rename the parameters to `overlay_ref_iterator` from `iter0` and `iter1` to `front` and `back`, and reverse their order. * Add a comment explaining why merge_ref_iterator_begin() can't do an is_empty_ref_iterator() optimization. * In "dir_iterator: new API for iterating over a directory tree": * Fix some comments. * Add a warning if `lstat()` fails for a reason other than `ENOENT`. This patch series applies on top of mh/split-under-lock. It can also be obtained from my GitHub repo [2] as branch "ref-iterators".
