I cannot reproduce this with today's trunk: I get the same font as the
one I've chosen from the menu using Set Default Font.

I don't see this in the doc string, please show the relevant text.  My
interpretation of the doc string is that when that function is called
interactively, it always sets font only of the currently selected
frame.  To do that for other frames, you need to call the function
non-interactively to be able to pass it a non-nil last arg.

> Note that the doc here includes (emacs) `Fonts'.

That doesn't seem to imply the font is changed on all frames, either.
