I propose that we prefix lines from STDERR with '! ' in the same way
that '# ' is used for diagnostics. wstat and exit can just be
wstat 256
exit 1
The problem with STDERR and exit is that we can't actually use them for
anything significant.
Otherwise when dealing with TAP streams that don't have a concept of an
exit code or a seperate error channel, the most common example being web
testing, we're left high and dry.
That's always been the main reason to intentionally ignore the exit code
at least.
