For now with:

grep-find-ignored-directories set to (".git" ".hg" "__pycache__")))

and

grep-find-ignored-files set to  (".#*" "*.o" "*.elc" "*.pyc")))

I get things like this:

-*- mode: grep; default-directory: "~/vit-projects-common-wiki/" -*-
Grep started at Fri Jul  8 08:48:12

grep  --exclude=.\#\* --exclude=\*.o --exclude=\*.elc --exclude=\*.pyc -i --color -nH -e emacs * .*
followed by the real grep output
without too many false positives

Sure one line of output would be better than 4 but its ok ... can live with it
