I didn't like this solution precisely because it doesn't rely on
character-cells units, and was explicitly looking for character
lengths/distances between arbitrary points.
If this calculation would be used in rigid-tabs for instance, I would
calculate different amount of spaces whether a variable-pitch font is
used or not, while my intention is much closer to (current-column).
But maybe I'm just arguing about nothing, and this is not really
something that can be generalized.
If you're using a variable pitch font, everything does down the drain
anyway.
