That check went out with the MPE compatibility stuff (dp-char and fp-char); 
the idea is that in MPE mode, you can enter just 13.3 and get a floating 
point value (no e needed).

I will add that check back in when fp-char and dp-char are equal, i.e. in 
Gforth mode.  As you have to set MPE-mode explicitely, that's following the 
principle of least surprise.  Gforth is more sloppy than MPE in MPE mode, 
following the Postel principle.

As VFX allows now for more than one separator char, I have to revisit that 
compatibility anyways.

The recognizer changes added a completely unrelated feature, you can now 
have engineering numbers, like "2u2" or "12k8".

BTW MPE mode and ANS mode: Stephen, you have two nice definitions in the 
*documentation* of the floating point library: ans-floats and mpe-floats.  
Take them out of the documentation and put them into the actual source code.  
These words are too useful!
