bug#32365: Interactive Highlighting: prefix arg as subexp selector

[Grégory Mounié]

 Here the patch for modifying Automatic Interactive Highlighting 
(hi-lock.el) for adding prefix-argument to highlight-regexp

 I add a line documenting the option in the corresponding 
hightlight-regexp documentation in doc/emacs/display.texi and a section 
in NEWS.


 Thanks a lot for the feedback and comments.

PS: it is even better with the patch
