[Remind-Fans] rem2html bug

[hymie at lactose.homelinux.net]

Greetings.

I found a bug in rem2html.

The remind man page says

       The SHADE special replaces the psshade() function.  Use it like this:
            REM Sat Sun SPECIAL SHADE 128
            REM Mon SPECIAL SHADE 255 0 0
       The SHADE keyword is followed by either one or three numbers, from 0 to
       255.  If one number is supplied, it  is  interpreted  as  a  grey-scale
       value  from  black  (0) to white (255).  If three numbers are supplied,
       they are interpreted as RGB components  from  minimum  (0)  to  maximum
       (255).   The example above shades weekends a fairly dark grey and makes
       Mondays a fully-saturated red.  (These  shadings  appear  in  calendars
       produced by Rem2PS, tkremind and rem2html.)

but rem2html does not honor the one-number version, only the three-number
version.  This patch fixes it.
