Re: string function - "format" function proposal

Hello

I am sending a updated version.

changes:

* tag %v removed from format function,
* proprietary tags %lq a iq removed from sprintf
* code cleaned

patch divided to two parts - format function and stringfunc (contains
sprintf function and substitute function)

Regards
