mem-modeline-fmt should be external

[BenjaminMoraga]

I was trying to edit the string showed by mem, but *mem-modline-fmt* is an internal variable. I don't understand why there are different options if you can choose between them. Also, I don't know enough lisp to solve the problem myself.

Do you want to send the PR adding the entry to the corresponding defpackage?

In the meantime external/internal symbols are meant to be a hint. The user can always access internal symbols in a package using ::. So you can use (setf mem::mem-modeline-fmt "...") in the meantime.

Thank you for your response. I will try to learn how to do it, I'm a newby to so many things. But I'm very interested in learning how to collaborate to projects using github.
