There's a parasite form feed character in email/mime/ 
(as well in python 2.4 and 2.5)

I caught that under vim (^L), it is located line 12 in the file,
the line before the class definition starts

PEP 8 does not call them parasites:

Python accepts the control-L (i.e. ^L) form feed character as
whitespace; Many tools treat these characters as page separators, so you
may use them to separate pages of related sections of your file.

so basically, if I open, it is perfectly OK to have is opened
in two pages in an editor ?

How weird ! 

PEP 8 also says that we should be consistent throughout a code base.

If this was the case everywhere in sdtlib, I'd say ok, but imho this
should be removed because this is the first time I see such a FF in there.

ok so it seems there are around 150 occurences, so I guess it is OK in
this particular code base :D

^L is used for a printer to insert a new blank page. But who really 
print a source code on a printer? Or does some editor have a special 
usage of this *control sequence*?

It looks like ^L is used in Lib/ as a hack for some editors so 
jump to the different classes, but there are other tools to jump to 
the classes.

Perhaps final comment here.  The email package was authored by Barry
Warsaw.  That's the way he prefers to break his code into sections.
Definitely neither parasitic nor accidental.
