I noticed that some of the conversion flags (%F & %X) are interpreted for
"backwards compatibility" rather than ANSI compliance.

I'm going to change this later this week.  There are no instances of
{,s,f,v,vs,vf}scanf that use either %F or %X in the entire source
tree, so either someone cleaned them up or those constructs weren't
very common.
