Just to be clear this is the default behavior of lgrep [sorry should have been 
clear when I said 'grep']

ie emacs started -Q
M-x lgrep
Giving all its 3 options
 1. Search for
 2. In files
 3. In directory 

This is its output

For rgrep its bigger:

Seems to be just the value of 'completion-ignored-extensions' -- which is fine
I'm just asking for it to go somewhere where its not (SO!) visible
