To me, all your changes sound very reasonable.  Bolshoye spasibo za

Well, the point of the minimal version was to give a reasonable
feature set with minimal memory footprint.  However, I think that's
more important for printf() (which could e.g. be used for quick
debugging hacks) while people short of memory will very likely avoid
scanf() completely.

My only concern about that is whether it's still C99 compliant that
way.  Curious, did you verify whether the standard imposes an
implementation-defined minimum here, and whether the 255 would still
fit?
