This doesn't actually change Willy's colour

As I said, useless poke... As for it not changing Willy's colour,
the code snippet is from the only place where the attributes are
set.

Okay, to be pedantic: it /does/ change Willy's colour, but not in
the simple way that people might imagine, i.e. the value you poke
into 38445 (JSW) or 37486 (MM Bug-Byte) is the OR-mask rather than
the actual INK colour of Willy.

Geoff Eddy's code for changing colour (based on JSW code at #95F8)
doesn't look to take into account the ramp's y offset, BTW.

It doesn't, as can be observed in "Good Skunk" in _Willy Takes a
Trip_. The ramps in that room are yellow, so Willy's feet correctly
appear yellow in that square, but appear white in the square to the
left of the ramp.

P.S. To correct a typo I made in Message 4079, the binary code for
yellow is of course 110, not 101 (cyan).
