[b38] wrong failure message on undiggable walls

[Ploppy]

Seems like an incredibly minor problem, but I'm reporting it just in case: trying to dig an undiggable wall with the Pick of Dwarven Emperors lets you dig for 13 turns, then returns: "stop reason: learnt lore." All other pickaxes I have at hand don't give a stop reason at all, which is at least a bit less confusing.

The same thing happens for me, but with "The Tooth of the Mouth". I guess "the lore" learned is "Don't dig in undiggable tiles! We have mouse-over info for a reason.".

Happens with any digger I think, mostly in vaults, but sometimes in mountains as well

I get a LUA error whenever I try to use either of those picks; I suspect the high speed is to blame.
