+
+ * A helper function that takes the contents of a commit object and

+ * "gc.autoPackLimit" when set to 1 should not trigger a repacking
+ when there is only one pack, but the code counted poorly and did
+ so.
+
+ * One part of "git am" had an oddball helper function that called
+ stuff from outside "his" as opposed to calling what we have "ours",
+ which was not gender-neutral and also inconsistent with the rest of
+ the system where outside stuff is usuall called "theirs" in

+ * Reference iterators
+ *
+ * A reference iterator encapsulates the state of an in-progress
+ * iteration over references. Create an instance of `struct
+ * ref_iterator` via one of the functions in this module.
+ *
+ * A freshly-created ref_iterator doesn't yet point at a reference. To
+ * advance the iterator, call ref_iterator_advance(). If successful,
+ * this sets the iterator's refname, oid, and flags fields to describe
+ * the next reference and returns ITER_OK. The data pointed at by
+ * refname and oid belong to the iterator; if you want to retain them
+ * after calling ref_iterator_advance() again or calling
+ * ref_iterator_abort(), you must make a copy. When the iteration has
+ * been exhausted, ref_iterator_advance() releases any resources
+ * assocated with the iteration, frees the ref_iterator object, and
+ * returns ITER_DONE. If you want to abort the iteration early, call
+ * ref_iterator_abort(), which also frees the ref_iterator object and
+ * any associated resources. If there was an internal error advancing
+ * to the next entry, ref_iterator_advance() aborts the iteration,
+ * frees the ref_iterator, and returns ITER_ERROR.
+ *
+ * The reference currently being looked at can be peeled by calling
+ * ref_iterator_peel(). This function is often faster than peel_ref(),
+ * so it should be preferred when iterating over references.
+ *
+ * Putting it all together, a typical iteration looks like this:
+ *
+ * int ok;
+ * struct ref_iterator *iter = ...;
+ *
+ * while ((ok = ref_iterator_advance(iter)) == ITER_OK) {
