Indeed.  'fit-frame-to-buffer' strips empty spaces at the beginning and
end of the buffer - it's aim is to make the frame occupy as little of
screen space as possible.  If 'resize-mini-frames' should handle
peculiarities as such display strings, it's probably better to write a
tailored function that handles them by calling 'window-text-pixel-size'
with the appropriate arguments.

But we can change the default behavior as well, or provide an appropriate
option.
