Problem using mimetools.encode

[Gilles Lenfant]

Seems to be a bug in the "quopri.py", the module that encodes/decodes
quoted-printable.

Here is "my" fix of this module: change the "quote" function and comment or
remove the first 3 lines like this:

==== quopri.py ====
...
def quote(c):
## if c == ESCAPE:
##  return ESCAPE * 2
## else:
  i = ord(c)
  return ESCAPE + HEX[i/16] + HEX[i%16]
...
==== end quopri.py ====

Perhaps this fix is partial but the encoding works now (MIME messages are
now correctly decoded by Outlook Express/Netscape Messenger/StarOffice
Mail).

I submitted this bug and fix to the Python group but I don't know if this
bug is still in the latest libraries (1.6 and 2.0b2)

Hope this fixes your problem.
