Hi, people.  Maybe someone will be kind enough to help me on this.

I receive many short messages which are created automatically on many
different systems, and filter them through a score file roughly looking like:


(
 ((and ("lines" 2 =)
       (or ;; [...]
	   ("body" "rapquot" s)
	   ;; [...]
	   ))
  -1000)
 )


The problem is that, depending on the distribution of cosmic rays along
Earth orbit, and probably other factors as well, I get a variable amount
of spurious white lines at end of messages, and even, sometimes, before
the first line.

The ideal would be that I go to each machine, recreate the exact conditions
of the invoice, try to reproduce the problem, understand it, and repair
all occurrences.  But I really do not have the time to do that now, and
I would like some other solution in the meantime.

I could use some bigger number of lines and use an inequality, but then,
the score might be decreased if a message happens to contain `rapquot'
together with something else which then interests me.  I would like the
score to be decreased /only/ if the message contains `rapquot' and nothing
else than white lines, say.  Do you have an idea how I could manage this?

I also do not know when and how lines are counted.  Is there a way to
arrange so that count excludes prior and subsequent white lines?  I guess
this approach might also solve my little problem.
