Well, the real point here is that ON_ERROR_STOP doesn't apply to
interactive input, and -c is evidently being considered to be
interactive.  You could argue that either way I suppose, but seeing
that -c can only issue a single command, implementing ON_ERROR_STOP
for it seems like largely a waste of effort.
