Subject: Please extend case-fold-search on-the-fly toggling

I have started using rgrep a lot recently, but I notice that the only way
to change its case sensitivity, other than manually editing the grep
command, is to change case-fold-search.

isearch now has the ability to toggle case-fold-search for a single search
using M-c; please could we have something like this in all (or at least
many more!) commands that use case-fold-search?
