+%% The algorithm used in determining whether to move a tag to a separate

+%% the space available is less than 2w (allowing for centering also), where
+%% w is the width of the tag, when it would be better to not move it unless
+%% the space is less than (w + 1 em), and also uncenter the main part of
+%% the display if necessary in order to fit the tag (this is the algorithm
+%% used by \eqno & \leqno).

+%% Need to check \split also. This bug has been reported before
+%% by other people also.
