Sorry, it's my horrible english. I don´t want to replace the
_gen_short_filename routine. The routine I have mailed is a new one
_lfn_get_short_fname, "get" no "gen". It return the real short file name of a
existent file.

No, sorry, this don't work to get the real sfn of a file.

I mailed about this to the general list, I want a copy utility who take care
about sfn and lfn of each file. So, you can copy all files to a new drive (by
example), make it the master and it work.
