It doesn't need escaping per-se (it's not a protected character - e.g.
"grep '-r'" won't work either. It's being interpreted as "please work
recursively".

As kish/krisk/Esse (sorry, couldn't figure out which was your name!!)
suggests, using a backslash works as it then passes \-r into grep.

However the easiest trick is that most programs will interpret "--" as
"end of all options". So you can use "grep -- -r".
