Nope, didn't completely figure out what expand returns for a file not 
existing/having access denied. I did figure out that all[4] contains the 
number of filenames being returned. For my 'more' function (And presumably 
any other function that takes only one file) I wasn't to concerned to just 
do the checking in the function (Which you will notice contains the cmd_cd 
code from the kernel wiztool).

If you do figure out the return values could you send me an email, I can't 
seem to figure out that particular bit of code.

Cheers,
