The best way for the new value of text-align to operate, imo, would
be as a 'match-parent' keyword. So for example,

   option, li, dl, dt { text-align: match-parent }

would give the consistent-bullet-position behavior. 'match-parent'
would be different from 'inherit' because 'inherit' triggers normal
inheritance -- inheriting the specified keyword value. 'match-parent'
would compute the 'start' and 'end' keywords against the parent's
direction, and result in either 'left' or 'right' as the computed
value of 'text-align' (which would then inherit to any children).
