sscanf exposed bugs

[Steven J Abner]

Sorry for the intrusion, I don't have newlib installed, but I do follow 
the code.
I happen to be working on a different version of the scanf() family. 
The test that was
just used for the patch was great! However, upon closer inspection of 
the scanf code,
would there possibly be missing code for "infinity" ???  I could 
convert and test your
code but thought it might be faster if you tested for the infinity 
cases yourself.
    Again, sorry for the intrusion.
