xffm & rename -0 addition

[Joe Stone]

hello !

Last week or so, there has been a discussion about the defaultname "new-0" of
a new created dir in xffm. I have no problem with that.

Today I tried file-renaming with xffm (3.99.1, rc1) the first time. 
When I try to rename (Ctrl-R,..) the name get's an additional "-0". 

Is this on purpose?
(I don't remember a situation, that I needed such a behavior.)

thanx
Joe
