I really wish we had different notation for equivalent flags. Exclusion
lists at this point are already overloaded and loko ugly (most important,
tgey force us to repeat the whole line). Consider

-b, --binary
-t, --text

where two lines are obviously incompatible. You can't write it using brace
notation; you need *four* lines! like

(-b --binary -t)--text...
(-b --binary --text)-t...

O.K. it could be shrtened to two lines but then quoting becomes unnatural
and too error prone.

Why? Assuming that main code for _arguments is in C (as I believe is the
case) it makes it quite easy to add call to gettext there. Current message
strings will the serve as keys to message catalog. Actually, GNU gettext
makes such transition transition natural.

We stil have strings that are not passed to C code, of course. But I doubt
that XML will help here. The problem is not to generate them but rather to
select at run time.
