[PATCH] handle non-integer sub-versions

[Aaron Bentley]

urlgrabber parses the Python version string, but doesn't handle all 
possibilities correctly; it assumes all integers, and some python 
installs will have something different.  For my install, sys.version 
reads: "2.3.4c1 (#4, Jul 20 2004, 08:57:39)
[GCC 2.95.4 20011002 (Debian prerelease)]"

The same info is available pre-parsed from sys.version_info.  Here's a 
patch that just does that:

+_python_version = sys.version_info
  if _python_version < [2, 4]: HANDLE_ERRORS = 1
  else: HANDLE_ERRORS = 0

If for some reason you really want to parse it yourself, you can do
_python_version = map(int, sys.version.split()[0].split('.')[:2])
