New primitive \matheqdirmode.
By default the short skip detection is not adapted to r2l typesetting and
that
hasn't been the case since the start of the project. Changing it could break
hacks that users came up with but when you set \matheqdirmode to a positive
value direction will be taken into account.

Several bug fixes (see ChangeLog).
