[Cfp-interest] String conversion functions

[Rajan Bhakta]

Sorry I had to leave a bit early yesterday, but here is what I was 
thinking of with regards to the format specifiers (making it easier for 
freestanding implementers to support our TS):

Replace

NOTE    If the conversion specifier (in the string pointed to by format) 
for x is not applicable to type double or long double, the behavior of 
strfromd or strfromld, respectively, is undefined.

with

NOTE  The format string must support specifying the precision, the 
floating point conversion specifiers (a, A, e, E, f, F, g, G), and the 
length modifier (L). An implementation may add any other format string 
support. If any other format string not explicitly supported by the 
implementation is present, the behaviour is undefined.

Recommended practice: The equivalent of hosted support for conversion 
specifiers for snprintf should be allowed.
