[Mailman-Users] Any way to disable wrapping of the subject header?

Mailman seems to like wrapping the e-mail subject when it gets too long
(78 chars I think.) Because this causes problems with many common
e-mail clients (Outlook, Thunderbird, etc.) is there any way to disable
The problem is that after "folding" the line (as RFC822 puts it) Mailman
uses a tab character to indent the line below. The RFC states that the
CRLF+whitespace combination should be replaced by just the whitespace
character used - and since Mailman uses CRLF+tab, after unfolding we end
up with a tab character in the middle of the e-mail subject.
Thunderbird displays this using ASCII encoding (so you get a little
round circle in the middle of the subject) whereas Outlook displays
nothing at all (so you get people pointing out that you forgot to put a
space in between those words.) Some MTAs seem to expand the tab into
eight spaces, leaving a large gap in the middle of the subject instead.
You can see examples of these in the messages posted to the list
yesterday, e.g. "Apache,<tab>mailman and ScriptAlias - not as documented"
The easiest solution (for me) would be to just disable folding of that
header, or alternatively to replace the tab with a space, so that e-mail
clients display a single space as originally intended by the author
instead of doing something funny with the tab character.
Does anyone know if there's a way to do this, or whereabouts in the code
I should start looking?
