It tries to rename files - top-bottom order...

gcmd could rename files in reverse way (bottom-top), but that wouldn't
work when renaming 02..04 -> 01..03 (sigh...)

The quick and dirty workaround here is to rename to different filename
(like _file-02 .. _file-04) and then to skip extra char.

Of course - you've got the point - there should be used some heuristics
here, but that would not rather happen before 1.4
