This looks strange, at first glance.
Do we set errno to 0 before ?
Or is there a trick that EPIPE can only be reached,
if it is "our" error ?

You are right and I'll fix it! 
Thanks for reminding me! 
Peff also noticed that some time ago:

Ben Peart's bp/sub-process-convert-filter topic also had the same
EPIPE issues in its earlier incarnation, IIRC.  I haven't looked at
this topic for some time, but I wonder if we can share code with it.
