Sure ;-) I'll wait a few days to see if there are any objections or
showstoppers.

I updated the patch yesterday, there was a fairly large change in
zipimport.c. If it were in CVS, this would have been the log msg:

   general:
   - incorporated patch from Paul Moore that adds a default zip
   archive path to sys.path on Windows (it was already there on
   unix). Thanks Paul!
   
   import.c:
   - matches latest version of PEP 302 (rev 1.3), regarding the
   new 'path' argument of importer.find_module(fullname, path=None)
   
   zipimporter.c
   - removed the subdir feature, which allowed the path to the
   zip archive to be extended with a subdirectory. PEP 273
   stated this was needed for package support (and only for
   that). However, with the new import hooks this is no longer
   true: a path item containing the plain zip archive path can
   also deal with submodules (find_module receives the full
   module name after all). Therefore a pkg.__path__ from a
   package loaded from a zip archive will contain the *plain*
   zip archive path.
   - as a consequence I could simplify and clean up lots of
   things (esp. zipimporter_init: eg. it no longer needs to
   check sys.path_importer_cache; yay). Getting rid of the
   zipimporter.prefix attribute altogether helped a lot in
   other places.
   - this change additionally enabled me to get rid of the
   restriction that zip paths must end in .ZIP or .zip; any
   extension (or even no extension) will now work.
   - implemented all the (optional) extensions of the Importer
   Protocol that the latest version of PEP 302 defines.

Merry Christmas everyone!
