Outmatched by MATCH

        The second rule below grabs spaces, even though they are excluded, by
omission from the match list:

OR=2147483647^0                     # Max score => immediate success. i.e. OR

   :0:                                    # (Topic|Subject) ~ project
   * $ $OR ^(X-)?Topic: +\/[^ ]+
                                          # Allow also "Re: Fw: xxx"
   * $ $OR ^Subject:[   ]*((re|fw):?[   ]*)+\/[0-9a-zA-Z_-]+

   Given that "It will  contain  all text  matching the regular expression
past the `\/' token", how does MATCH then come to hold "Fw: n2ip_nms",
as logged:

procmail: Score:       0       0 "^(X-)?Topic: +\/[^ ]+"
procmail: Assigning "MATCH="
procmail: Matched "Fw: n2ip_nms"
procmail: Score: 2147483647 2147483647 "^Subject:[      ]*((re|fw):?[   
]*)+\/[0-9a-zA-Z_-]+"
procmail: Executing " ls /export/projects | grep -i "$MATCH""
procmail: Non-zero exitcode (1) from " ls /export/projects | grep -i
"$MATCH""
procmail: No match on " ls /export/projects | grep -i "$MATCH""

        Repeating the experiment, with explicit exclusion generates the same
        result:

procmail: Matched "Fw: n2ip_nms"
procmail: Score: 2147483647 2147483647 "^Subject:[      ]*((re|fwd?):?[
]*)+\/[^        :]+"


        How can it do that? (Or, perhaps more to the point, what am I
        doing in an unprocmailian way? :-(

        For what it's worth, when I try the regex with gawk, its matching
        grabs things OK:

        $ gawk '{match($0,/^Subject:[   ]*((Re|Fw):?[   
]*)+([0-9a-zA-Z_-]+)/,A); print A[3]}'
        Subject:  Re: Fw: n2ip_nms
        n2ip_nms
        
Regards,
Erik
