Re: [PATCH 3/5] merge-recursive: clarify the rename_dir/RENAME_DIR meaning

> We had an enum of rename types which included RENAME_DIR; this name felt
> misleading since it was not about an entire directory but was a status for
> each individual file add that occurred within a renamed directory.  Since
> this type is for signifying that the files in question were being renamed
> due to directory rename detection, rename this enum value to
> RENAME_VIA_DIR.  Make a similar change to the conflict_rename_dir()
> function, and add a comment to the top of that function explaining its
> purpose (it may not be quite as obvious as for the other
> conflict_rename_*() functions).
