[Omake] FS case-sensitivity testing - if the name is non-alpha, should we still test.

Hmm, could be.  I don't quite understand your example, but in the end  
it is the equality we care about.  So, even if there is a numeric  
name along the path, we still care, for example, if the following are  
different.

     /usr/kde/3.5/bin/KONSOLE
     /usr/kde/3.5/BIN/konsole

Also, we should probably consider using access(2) (or similar, based  
on stat) to detect the case where the directory is not writable.   
This won't help if the directory looks writable but the fs is read- 
only, but I think we would still catch the vast majority of cases.
