Yes, the negation is a bit confusing, just for being allowed to say
  if (run_command(foo) < 0)

since you end up having to store and re-negate anyway to get the actual code. Plus the value of errno is untrustworthy, since we may have been doing cleanup calls.

I think it is nice to differentiate between an exit code from the sub-program and our own error, though. See my updated series for what I think is a reasonable one-liner fix.
