Allow w5 while standing in the dark
Title says it all
I was about to submit a bug report because I got blinded by a trap in a dark room, and could not w5 my way out of blindness because I was in the dark. (D'uh.) But then I thought that what is the reason anyway to not allow waiting on spot just because you are in a dark room? Couldn't think of any, since any unexpected events interrupt it anyway.
