Honestly, i wasn't aware of `C-c C-a' functionality so i didn't 
realized that aim of the patch.

I agree, `C-c C-a' or `M-k' is a good thing to have fixed.  Eventually, i 
would like to use such features.

It seems you are right.  IMO, we must aim to have the `C-c C-a' stuff 
fixed, but preserving those behaviours that we are complaining here.
Until this aim is fulfilled, i would like to pospone this patch, or 
to have a temporary solution as Mark's one in this thread.
