I've been confused enough already.  It would be nice to get this right
once and for all.

We would add an alias, obviously.

I forgot that it was Joe Corneli who asked for this in another thread.
But once we have a function like `window-max-characters-per-line' it
would make sense to have it consider the maximum width of a proportional
font character as well and we'd fix his problem as well

BTW, do we have some character or letter spacing which we should
consider as well?  IIRC somone asked here for an orthogonal function
that would consider line spacing.
