ReproducibleScript:
% lsort -integer f
f

DesiredBehavior:
i'd rather get an error message!



An error would be correct in this case, while the current source
just assumes this is a quick noop.

Hmm.  This needs a rewrite of the manual page to state that the conversion
to integer/float happens as part of the comparison, and not prior to the
overall sort (which I believe to be the correct behaviour.)

I don't know whether an error is correct; surely the options just control
the nature of the ordering function.  No ordering required, all ordering
functions are happy.  Plus, how could you test in the first place?  Calling
the ordering function with the same element for both values is a much worse
idea, particularly if the ordering function was specified using -command...
