On a related note, since "The regexp engine has to keep track
of all of those possibilities", will one day exist a possibility to
backtrack and find the *next* match, in the case that the first one
does not succeed completely. Can you add this to the "Wish List"?
This may be too much for procmail. Maybe I should look at something
else. Any suggestions?

Yes! For example:
:0
* 9876543210^0 $ ^(From|Subject):.*\/\<(${regexp})s?\>.*$
* 9876543210^0 B ?? $ ()^\/.*($.*)?\<(${regexp})s?\>.*($.*)?
{
LINES = $MATCH
}
:0 A
*$ MATCH ?? ()\/$regexp
{
NAME = $MATCH
LOG = "--> Name = $NAME <--$NL"
}
# Baier is one of the patterns in $regexp
:0 a:
* NAME ?? Baier
* ! LINES ?? Research: SOBEK, BAIER/BEIER
$outfile
In this case, I would like to continue the initial match from the tail
of the first find. Maybe all that would be necessary would be a
"goto" operator or "next match" operator, that would continue the
process where the last was left off. May this be possible?

Maybe I would need such a `mongo' regexp compiler!
