Hello!

My customisation has

  '(comint-prompt-regexp "^[a-z]+ [0-9]+ /\\\\ " t)
  '(shell-prompt-pattern "^[a-z]+ [0-9]+ /\\\\ ")
  '(comint-highlight-prompt ((t (:background  
"FloralWhite" :foreground "DarkViolet" :weight bold))))

Sometimes I locate items and sort them by killing and yanking the  
lines they're on. When I yank such a line just above the prompt,  
i.e., the cursor is in column 0 at the prompt's beginning, the  
prompt's fontification is extended over the yanked line as this  
screenshot shows:

It works with keyboard as well as with mouse.
