[...]  Just want to say that strfrom* family is long overdue, but
still appear incomplete.  The guiding principle should be that all
format specifiers available in printf() with sole exception of %s
should be provided as strfrom* as well.

My practical motivation is space-constrained environments, where I
possibly want one or two or three formatters.  sprintf() gives me all
or nothing and all can be too expensive.  Many embedded environments
have big and small variants of sprintf that can be chosen at link
time, but what's in small variant does not necessarily match a set
that I want in my specific project.  And is not necessarily well
documented.

Okay, I see now where you're coming from, although I'm not sure that
the strfrom*() functions will give you what you want (in terms of
memory footprint, etc).  But I get your motivation.

Question:  which of the four formats (%A, %E, %F, %G) are ones you
expect to use?  Also I'm curious: do all of your target platforms
use IEEE floating point, or do some use other representations?
