[texhax] the best way to typeset

[Philip TAYLOR]

Maybe something like :

     \def oneortwo #1#2%
         {\setbox 0 = \hbox {$#1 = #2$}
          \ifdim \wd 0 > \linewidth
                % generate two rows of an \halign
          \else
                % generate one row of an \halign
          \fi
         }

and allow the \halign to worry about working out where
the tab should go ?
