We already represent information that is for the format string as
existing globals. It means that, if we ever want to make the program
accept and use more than one format string, we can't.  We need one
set of them for each such format string before we can use more than

If you want to solve that problem, complaining by using a subjective
word "ugly" does not help us much.  The right approach to the
solution would be to first think what each global really means and
decide which ones are per-format properties.  Then turn them into a
proper abstraction by defining a structure to hold the currently
considered format string and these various "per format string"

Once you do that, you can optionally make the code pass that single
structure around, and that will remove the global, but I think that
step can wait until we actually find a need for it.
