I just noticed that the following passage in RFC 822:

equivalent to the LWSP-char.
is not being honored by the email module. The following two invocations
of message_from_string() should return the same value, but that's not
what happens:
>>> import email
>>> email.message_from_string("Subject: blah").get('SUBJECT')
'blah'
>>> email.message_from_string("Subject:\n blah").get('SUBJECT')
' blah'
Note the space in front of the second value returned, but missing from
the first. Can someone convince me that this is not a bug?
That's correct, according to my reading of RFC 822 (I doubt it's
changed so I didn't bother to look up what the latest RFC on that
subject is.)
The RFC says that in a folded line the whitespace on the following
line is considered a part of the line.
Thanks for responding. I think your interpretation of the RFC is the
same is mine. What I'm saying is that by not returning the same value
in the two cases above the module is not "regarding CRLF immediately
followed by a LWSP-char as equivalent to the LWSP-char."
