Summary: email.Header misparses mixed headers
Initial Comment:
email.Header.decode_header() misparses headers with
both encoded an unencoded words. This example from RFC2047
=?ISO-8859-1?Q?Andr=E9?= Pirard <[EMAIL PROTECTED]>
gets parsed as
AndréPirard <[EMAIL PROTECTED]>
where there should obviously be a space between André
and Pirard. RFC2047 says to ignore spaces between
encoded words (but not between encoded and unencoded
words, though it doesn't explicitly say so from what I
could find, and obviously not between unencoded words).
Also, I see it's trying to handle continuation lines,
but it only does it if there are encoded words in the
continuation line. It barfs badly on this test case:
'Re: =?mac-iceland?q?r=8Aksm=9Arg=8Cs?= baz\n foo bar
=?mac-iceland?q?r=8Aksm=9Arg=8Cs?='
I think I'll just do a patch...

P.S. It seems at least remotely related to Bug#552957

I am using python 2.4 and still have this problem. To be
more exact, line 73 in Header.py still strips the parts.
Is there a reason for this not being fixed?

The first bug is still there... With version 1.19 from CVS I
get this with my example:
>>> print
unicode(Header.make_header(Header.decode_header('=?ISO-8859-1?Q?Andr=E9?=
Pirard <[EMAIL PROTECTED]>'))).encode('latin-1')
AndréPirard <[EMAIL PROTECTED]>
(The problem is that whitespaces get stripped of on line 91:
unenc = parts.pop(0).strip()
before we know whether they are significant or not.
The continuation line bug seems to be fixed however.

The first bug above has already been fixed in email 2.5
(python 2.3 cvs). The second pointed to a real bug, now
fixed I believe.
