Not sure if I understand this correctly. Do you mean you would do the
actual formatting on the geos side and pass the formatted string as
'fmt' then? That would work if you're ok with the subtle behavioural
change. Seems unlikely that anyone would count on the exact contents of
'fmt' and the parameter list, but you never know...

Memory allocation for the formatted string shifts to geos then as well;
do you think that's an issue?
