rgrep uses "xargs -0 -e grep -i -nH -e ..." but
do you really want to make the '[-E eof-str] [-e[eof-str]]' = "grep"?

Do you really want to use xargs -e at all?
If so why not xargs -E?

Maybe this is confusion with grep -e.

No, and it isn't done, since that would be "xargs -egrep" or
"xargs -E grep".

Because -E requires a an eof-string while -e does not.

I suppose not, but the -e option for xargs is probably superfluous.  It
had always been used since grep-find was introduced in Emacs 20; anybody
who remembers the reason (if any) for it?
