rgrep.el breaks syntax rule in fish-shell

The find and grep command generated by rgrep is not working for the fish-shell, as {, } needed to be escaped as required in doc.

In one example below, the very last few words ... -exec grep -i -nH -e foo {} + causes fish-shell to raise error. Change it to -exec grep -i -nH -e foo \{\} + will work.

The escaped version works in sh/bash as well.
