These arguments to the `WC` macro define registers that are never
interpolated.  They therefore have no effect.

Their descriptions are hard for me to understand.  The DWB mm manual doesn't
leave me much wiser.  It defines this flag in similar terms but tellingly
avoids discussing it in its example of the WC macro's usage.

Why would you _not_ have a break, meaning a line break, when popping a
floating display?

A display implies a break anyway.  Always.  Everywhere.

What is the deal with this feature?

Can we just drop it?  It's done nothing for ~30 years with no evident
complaint anyway.
