The benefit of this patch is that 'query-command-line-options' gains a
fix where three bogus entries are replaced by their actual command line
spelling.  The drawback is that anyone that doesn't pay attention to the
ABI break announcement, and expects -readconfig and friends to work
while using the old spelling, is in for a surprise.  But since we have
prominently documented the change, and since consistency makes life
nicer, I'm in favor of this patch.
