Hmm, that says there is allowed to be a difference but not why there is a 

The quote from the C standard would allow both e,f and g to have the same 

In the original K&R(pre ANSI) it simply says %g is the shorter of %f and %e 
no hint of any other modification. Given that the logical implementation for 
would be to use %e/%f format as required but for some odd reason its been
implemented differently.

So its not really a bug, since the spac allows for it, but is still strange
