It does sound "too sweet to be true", but if you say it's so, I'm all
too happy to believe you.
I do think we'll need to provide better "visual movement" commands, but
these should really focus on being commands, like the current
line-move stuff.
It does point to a relevant detail: we had intended to (and someone
started working on) using the display iterator to (re)implement
current-column so as to take things like proportional fonts (and
variable font sizes) into account and return pixel-precise info in the
form of floating-point column numbers. In light of your message, it
seems that maybe this kind of functionality should not replace the
current code.
