nethack/src/zap.c
PatR f0370f5f86 you feel {a,an unexpected} draft 
Move the message given when a monster digs through a closed door
or a secret corridor into a separate routine.  In theory, nethack
should determine whether there is a path between the new opening
and the hero's location in order to decide whether a draft can
be felt.  (I don't think anyone is likely to implement that--I'm
certainly not.  Checking whether the hero is in a room with no
breaches in its walls could at least catch being inside a vault.)

While at it, add some USA-centric puns about feeling the prospect
of imminent military conscription instead of air current if it
happens while hallucinating.

* Recognizing unseen wands by zapping: in 3.4.3 and earlier, zapping

* changed; now such wands won't be discovered. But if the type is
* already discovered, then the individual wand whose effect was just
* observed will be flagged as if seen. [You already know wands of
* striking; you zap "a wand" and observe striking effect (presumeably
* by sound or touch); it'll become shown in inventory as "a wand of
* striking".]
*
* Unfortunately, the new behavior isn't really correct either. There
* should be an `eknown' bit for "effect known" added for wands (and
* for potions since quaffing one of a stack is similar) so that the
* particular wand which has been zapped would have its type become
* known (it would change from "a wand" to "a wand of striking", for
* example) without the type becoming discovered or other unknown wands
* of that type showing additional information. When blindness ends,
* all objects in inventory with the eknown bit set would be discovered
* and other items of the same type would become known as such.
