[Groff] [bug] fractional point sizes and eqn

[Tadziu Hoffmann]

Since groff allows fractional point sizes, the register
".s" returns point sizes as decimal numbers.  Eqn tries
to saves these sizes in normal number registers which,
however, can hold only integers and therefore truncate
the value.  Thus, when the point size is restored from
such a saved value (for example, after an inline equation),
we end up with a different size than we began with if a
non-integer pont size was in effect before.

(Fix available.)
