How do 1 and 2 differ? FWIW, the use case that setuptools has (and for
which it currently incorrectly uses normpath) is number 2.
4. Return the case of a filename in some arbitrarily-chosen canonical
form which does not depend on the file system?
This is what normpath does, but only if you're on Windows ;-)
I still don't really get the use case of normpath in its current form,
at all...
Various people have posted links to recipes that solve case #2. Note
though that this necessarily demands that if the file doesn't exist, it
should raise an exception.
Fine by me, shame it seems to require iteration to find an answer though :-S
The very concept of canonical form for file names is troublesome.
I would have thought "whatever is shown when doing an ls/dir/etc"
(and don't be smart and think about mentioning that oyu can get dir to
output 8.3 as well as the full path ;-) )
