On the joyous occasion of Python 3000's release my friends & I were
playing with "import antigravity" and it failed for someone with the
following traceback (anonymized):
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/.../lib/python3.0/antigravity.py", line 4, in <module>
 webbrowser.open("http://xkcd.com/353/")

 if browser.open(url, new, autoraise):
 File "/.../lib/python3.0/webbrowser.py", line 275, in open
 success = self._invoke(args, True, autoraise)
 File "/.../lib/python3.0/webbrowser.py", line 226, in _invoke
 inout = open(os.devnull, "r+")
 File "/.../lib/python3.0/webbrowser.py", line 61, in open

 "expected 0, 1, or 2, got %s" % new)
webbrowser.Error: Bad 'new' parameter to open(); expected 0, 1, or 2, got r+
I believe the following patch (against branches/release30-maint) fixes
it cleanly:
