[Agreed]

[Misses device specials etc. maybe a good thing, but we're here for the total
solution]
Which all brings me to my final thought. Given that '-R' is smart about .files
in subdirectories listed on the command line, we can use this:-
chmod -R 0644 .
as a replacement for the otherwise excellent ls -A | xargs chmod
Everyone happy now ?

P.S. small prize to the first person that spots the minute deliberate error in
this. Larger prize if they provide a fix that's still more elegant than Nate's
contribution.
