As I said: 

   ...you can call it an enhancement request...

   And until the requested enhancement is made there is a doc
   problem for `C-M-w', as it does not call out the fact that it
   doesn't append text selected with the mouse. AFAIK, there is no
   way to use `C-M-w' to cause a mouse selection to be appended
   to what was at the head of the kill-ring before that selection
   was made.
