I was thinking that, but I seem to remember a system that let you type 
"cd ..." to get to the parent's parent, (and "cd ...." to get to the 
parent's parent's parent,) and I didn't want to let that slip through, 
on the off chance that that system still exists...

should we move to regular expressions?
assert not re.match( '..+/', f )
assert not re.search( '/..+/', f )
