They don't seem to offer anything which sprintf(3) doesn't already so I
couldn't add the extra features with these. The man page on Linux says
that they are obsolete even.

Also, I don't think we should be handling locales unless asked to with a
flag because it is common for programs to need input which isn't in a
local format.

I could update convfloat() etc to just use sprintf() more easily and
with just as good results. With that, I could support -s and -z but not
the other extras which is why I thought about doing the conversion
entirely manually.
