mdwtab.dtx: Cope when \if@leqno is frobbed dynamically.

Thanks to Christian Cornelssen for this change.

I considered adding user commands for twiddling \if@leqno (and
\if@fleqn), but I decided against it because the `leqno' and `fleqn'
options do a notionally document-class-specific thing which (in common
cases) involves a complicated rewrite of the `equation' environment and
the \[...\] commands, which I really don't want to get into right now.
