Yes, but:

H:\>echo foo > TeSt.txt
...>>> import os.path
 >>> os.path.realpath('test.txt')
'H:\\test.txt'
 >>> os.path.normcase('TeSt.txt')
'test.txt'

Both feel unsatisfying to me :-S

How can I get 'TeSt.txt' from 'test.txt' (which feels like the contract 
normcase *should* have...)

But what value does that add over just doing a .lower() on the path?
