Slight internal representation change of string-only exceptions.

One upshot of all this is that (throw 'foo "msg") now
does exactly the same thing as (throwf 'foo "msg").
A message-only exception really is a one-string exception argument
list ("message ..."), like the documentation says.

* unwind.h (struct uw_catch): exception member renamed to args.
(uw_catch): Macro follows structure member rename.

* eval.c (op_catch): Removed now unnecessary kludge of turning non-list
exception argument list into a one-element argument list.

* match.c (v_try): Similar hack to the one in op_catch
removed here.

* unwind.c (uw_unwind_to_exit_point, uw_push_catch): Follows rename of
exception member.
(uw_throw): The exception parameter is renamed to args.  The kludge
removed from op_catch re-appears here, because numerous calls
to uw_throw just pass a string as args. It's less of a kludge here
because this is the master entry point to exception processing,
and it straightens out the representation right away.
The exception arguments or message are printed in a clearer way.

 	Serious bugfix in the op macro, and derived macro, in
 	the handling of missing meta-numbers (for
 	instance (op ... @1 .. @3): 1 and 3 occur, but not 2.
