Subject: [PATCH] lit and unlit corridors The default symbol for lit and unlit
 corridors are the same.  This makes the lit_corridor option a no-op where the
 defaults are used and also means that using a light scroll/spell a corridor
 has no obvious effect.  To address that, I special-cased the lit corridor
 symbol and change its color to bright white when its the same symbol as the
 unlit corridor symbol (I didn't change the default color since I thought that
 made the lit corridor look strange using the windows console interface).
