The poor man's solution is to pipe the output through

     grep --invert-match --regexp="multiple ([0-9]*) blanks"

I agree with Henning about the hyphen option. This often (usually?)  
means "don't read from a file but from stdin".


Underestimating the novelty of the future is a time-honored tradition.
