Far too many I's in 5.0
Is anyone else getting sick of the levels being taken over by Remembered Unseen Creatures? Especially when you have clairvoyance... look at this nonsense:
It's at least a bug that clairvoyance doesn't get rid of the existing I's when you detect a bunch more, since you're supposedly being given insight as to where the monsters are and aren't. For example, those houses that are full of I's on every space almost certainly contain exactly one (1) gnome; they've just been in different spots each time my clairvoyance kicked in.
Is there a way to get rid of them all at once? ^R to redraw the screen doesn't do it. Or even an option to stop them being there in the first place? At the very least, if you knew that an I represented a visible creature - as you do a lot of the time - it should disappear when you have a line of sight to that space. AFAICT the only way to get rid of them is to 'm'ove through them (just stepping into them wastes a turn "attacking thin air"), and even that is likely to waste several turns if you weren't walking that way anyway.
If such a command (or option, or whatever) doesn't exist, and a friendly dev or patchy person is reading this, can we have one?
