Three examples:
git grep -e Junio --and -e Dscho --and -e Peff
is different from
grep "Junio.*Dscho.*Peff"
in that the latter wouldn't find a line that has these names in different
order. You can of course give permutations explicitly, like
grep -e "Junio.*Dscho.*Peff" \
-e "Dscho.*Junio.*Peff" \
...
-e "Peff.*Dscho.*Junio"
I don't know how you would do these with "grep":
git grep -e Junio --and -e Dscho --and --not -e Linus
git grep --all-match -e Junio -e Dscho
