list-load-path-shadows results be clickable..

[D. Goel]

i would like to work on making the results of M-x
list-load-path-shadows clickable----

viz. when you press RET on a result, it displays the 'diff -cw' among
 the two files...

Wanted the blessings of this list before i start that :) , and any
suggestions..

====================================================
My plan is as follows:  Consider this result-->

 ~/emacs/ee hides ~/ee

i want to make all terms above clickable--->

Clicking ~/emacs/ee will show me that file in the other window..
Clicking ~/ee will show me that file in another window.
finally, clicking on 'hides' will show the 'diff -cw'.

Comments?   

(Or does anyone know if this has been already done somewhere that i don't know
of? )

====================================================

(IMHO, that will be very useful---
 often the shadows arise because i may have made changes to some
 default file and stored the modified version in my ~/emacs/ while i
 am waiting for the patch to be approved :)...
 
 and i very often feel a need to see the diff -cw between the files
 shadowing each other..)

====================================================
