The best of both worlds! We already need a similar scheme for fonts,
where `font' can take the place of (and overrides?) the values of
`font.family', `font.size', `font.style', etc., so `border.*' would
not be anything new.

The interaction between `border' and elements that do not start and
end with a line break should be defined: what does `EM:border.style'
mean? I suggest that `border' only causes those sides to be drawn that
are well-defined. In detail:

1. an element with both a break before and a break after it
   -> all four sides apply.

2. an element with a break before but not after it
   -> only the top side of the border is drawn.

3. an element with a break after but not before it
   -> only the bottom side is drawn.

4. an element with neither a break before nor after it
   -> all border properties are ignored.
