This looks OK to me: it says we display 4 characters in one face and 1
more in another. Which agrees with pgrow and with what I understand
should happen here: the 4 characters T O D O are displayed using the
font of the variable-pitch face, and the blank space after it is
displayed using the default face.
What do you see on the screen in this case? Please describe the
visual appearance of each character in the case of fundamental-mode,
and perhaps also show a screenshot of the window as it is displayed
when the mouse-highlight becomes visible during this scenario.
Thanks.
