For example, the original Subject header may look like this:

Second-line
Please note that there is only one space character in it. When I let
procmail do
:0
* $ ^subject:[$WS]+\/.+
{
av_SUBJECT = $MATCH
}
where $WS holds the SPACE and TAB character, this results in
Assigning "av_SUBJECT==?utf-8?q?First-line-followed-by-one-space?= Second-line"
Now the unfolded Subject got an additional space at the place the
newline was. How can I avoid replacing all these newlines by a space?
I'd say punt.
:0
* $ ^subject:[$WS]+\/.+
{
av_SUBJECT = `echo "$MATCH" | sed 's/ */ /g'`
}
[can't remember the right syntax for tr -s right now]
You're not going to be able to do it within procmail, because for
scanning the head, procmail's regexp engine treats continuation newlines
as spaces. When you extract into $MATCH, there's no way to tell those
two spaces from a real pair of adjacent spaces that were there before.
