Once upon a time, I put together a little function
that tries to find the canonical filename for a given
pathname on POSIX. I've finally gotten around to
turning it into a proper patch with documentation.
On non-POSIX, I made it an alias for 'abspath', as
that's the behavior on POSIX when no symlinks are
encountered in the path.
Example:
>>> os.path.realpath('/usr/bin/X11/X')
'/usr/X11R6/bin/X'

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.
I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.
The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings. Hope this is
okay.
* Lib/macpath.py: don't return trailing colon for dirname()
(XXX won't do for volume names -- but otherwise glob(':*:*.py')
loops forever)
* Lib/traceback.py: print SyntaxError correctly
* Lib/stat.py: moved to posixstat.py; added macstat.py which has
the constants for the Mac; and created new stat.py which includes
the right one
* Lib/urllib.py: fix caching bug (by disabling the cache)
* changed eval() into getattr() in cmd.py
* added dirname(), basename() and (dummy) normath() to macpath.py
* renamed nntp.py to nntplib.py
* Made string.index() compatible with strop.index()
* Make string.atoi('') raise string.atoi_error rather than ValueError
* Added dirname() and normpath() to posixpath.
