Thanks for the clarification.

Sounds good to me. Would we also want to include something in the menu to do the
same thing for the frame? Or perhaps for all frames? Or perhaps for all buffers
of the same mode?

I'm thinking that what users will typically want to do is one of these: 

1. Change the font for the current buffer (what you propose).
2. Change the font for the current frame (what we used to have).
3. Change the font for all buffers that have the same mode as the
   current buffer.

We might accommodate all of these use cases with the same menu items, just by
including a multiple-choice set of radio buttons at the end of the menu:

(.) Current Buffer
( ) Current Frame
( ) Buffers with Current Mode

The last of these would affect also future buffers in the current mode, not just
existing buffers in that mode.

Regardless of whether this idea appeals to people, I am in favor of the change
you proposed: current buffer instead of current frame.

I didn't quite understand that part.
