shouldn't prompt printing be smarter?

[Francesco Montorsi]

Hi,
   I think you all have encountered this: do a "cat somefile" where 
"somefile" is a text file _without_ a final newline. You'll see the 
prompt is printed both at the end of the text printed by 'cat' and then, 
also at the beginning of that same line.

I'm attaching a screenshot which should make it clear.

This results in a very weird/annoying effect.

I think it would be great if bash before printing the prompt could do a 
simple check: if the cursor is not positioned in the first column of the 
terminal, then prepend the prompt with a newline.

Thoughts?

Thanks,
Francesco
