The consequence will be that renaming all files in one directory (and "all" can even be a single file) will temporarily delete and recreate that directory. My proposed change of index sort and processing order would take care of that without requiring multiple passes, at the cost of changing the index format and processing. I think that it would be a sound long-term solution. Anyway, once directories can be tracked (again necessitating a change of index format), surprising directory deletion and recreation should become less of an issue, but it won't help with projects that continue not tracking directories (presumably most patch-based workflows). -- David Kastrup, Kriemhildstr. 15, 44793 Bochum - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
