If you type over the existing autofill but with a different case, you see what 
was there originally, not what you're typing.  It's quite confusing when what 
you type is not what you see.

Aside from the fact that it requires someone to go to the effort of 
implementing my suggestion that an initial backspace cancels autofill, are 
there any problems with the idea itself?
