Exclude Directories from os.walk

[D]

Ok, my brain's apparently not working right today.. what I'd like to
do is allow the user to specify a directory to exclude (ex- "C:\temp
\test") - then, when os.walk gets to "C:\temp\test", it excludes that
directory and all its subdirectories (so, "C:\temp\mytest\test" should
still be recursed).  Isn't what's posted above keying just upon the
final subdirectory (i.e. "test") instead of the full path as a whole?
