[BusyBox] Problem with ls

[Richard June]

Using the 0.47 version of busy box I'm having a problem, ls -aR causes
an infinate loop, it recurses '.'.  I know *why* it's doing this, but
fixing it is a little bit different, I'm not overly familiar with all of
the structures, nor have I completely wrapped my head around the ls
code. I think the spot that is broken is showdirs, any preferences on
*how* it should be fixed?
