extended diagnostict in the logfil

When I turn on extended diagnostic (VERBOSE = yes) the logfiles get
cluttered up by the different subprocesses:

:0c {
  ...
}
This will (as I see it) start a new subprocess for the commands within {}
while the original procmail process will continue.

This makes it very hard to see what comes from which procmail line.
Is there a way to "liniarize" this, so the original procmail command will
not continue until the subprosses has stoped? Or to add line numbers in
the from the recipe file.

------------------------------------------------------------------------
Is there anotherway than the following to junk mail:

:0
/dev/null

or 
:0
{}

Kind Regards Jepser.
