Breaks Solaris. We need a different approach. I presume the binary tools
that ship with commercial unices are not up to the tasks we expect
them. They expect text, we feed binary, this must fail. I've had much
"fun" with sed and head on Solaris already which is why I wrote
tests/dumbhead.c -- I couldn't find a tool that would handle \0
properly.

I fear we now need a dumbgrep...
