Summary: zipfile: inconsistent filenames with InfipZip "unzip"

Initial Comment:
zipfile.py gives filenames inconsistent with the
InfoZIP "unzip" utility for certain ZIP files.  My
source is an email virus, so the ZIP files are almost
certainl malformed.  Nevertheless, it would be nice if
"unzip -l" and ZipFile.namelist() gave consistent
filenames.

Example: the attached Demo.zip (extracted from an email
virus caught on mail.python.org) looks like this
according to InfoZip:

$ unzip -l /tmp/Demo.zip 
Archive:  /tmp/Demo.zip
  Length     Date   Time    Name
 --------    ----   ----    ----
    44544  01-26-03 20:49  
DOCUME~1\CHRISS~1\LOCALS~1\Temp\Demo.exe
 --------                   -------
    44544                   1 file

But according to ZipFile.namelist(), the name of that
file is:
 
DOCUME~1\CHRISS~1\LOCALS~1\Temp\Demo.exescr000000000000000000.txt

Getting the same result with Python 2.2.2 and a
~2-week-old build of 2.3 CVS.
