I'm not familiar offhand with what 2.0.x did WRT folding subject
headers, but maybe it didn't.

The only thing I see in this subject is RFC 2822 folding (i.e. the
newline followed by whitespace (a tab in this case) that is the
standard way of folding long headers. I see only spaces between words.
I see nothing that would cause your MUA (client) to show
'undisplayable' characters.

As I indicated in my previous post, the newline comes from folding of a
long subject in a standard way. My MUA is going to do this to this
message which is going directly to you, not through Mailman. What do
you see in your MUA as the subject of this message?
