pgawk 3.1.80: warning: error writing standard output (No error)

[Hermann Peifer]

Hi,

A somewhat funny warning/error message for pgawk 3.1.80, which seems to 
be related to the subsequent usage of head -9 and head -99. Probably 
some buffer issue related to writing stuff into --profile=colorise.out

(I was using awk 3.1.80 under Cygwin, I have to admit).
