?I wanted to get rid of extra junk from unix filenames.

Why bother?

?To that end, I tranform:
?
?	a//c            -> a/c
?	a/./c           -> a/c
?	a/c/.           -> a/c
?	a/b/../c        -> a/c
?	a/c/d/..        -> a/c

Beware: a/b/../c is not always a/c if b is a symlink.
This bothers some people, but not others.
