The minimum right margin would be page-width - (left-margin +
maximim-line-width).

For right-justification, the right margin would always be at its minimum
value.

For left-justification, the left margin would always be at its minimum
value.

For centering, the difference between the left margin and its minimum value
would be the same as the difference between the right margin and its minimum
value.

I don't know if anyone is going to be touching this stuff.  AFAICS, this is
all just discussion about some hoped-for future behavior.  I consider it a
major change to implement this, and I don't imagine it will happen in the
near future.

I can understand wanting to have m be something other than 2 (really, I can
only imagine it being some even number), but why would you ever want to have
b be something other than 1?  The page turn always comes at the end of some
page, and the there is a one-page difference between the page before the
turn and the page after the turn, isn't there?
