two land mine bits

Noticed when investigating one of the killer reason bugs recently
reported:  a land mine explosion shouldn't create a concealed pit trap;
make a revealed pit instead.  And while testing that, I noticed that the
"Kaboom" message given when pushing a boulder onto a land mine was given
while the map still showed the boulder at its original location even
though it had actually been moved already.  It's a little odd that you
get hit by shrapnel at your original position--as if you're shoving the
boulder ahead of you and then pausing a moment before stepping into its
former location--but that's trickier to fix; sometimes you won't advance
due to there being multiple boulders present (in that case you evidently
do shove the boulder instead of performing a steady push, so maybe the
current behavior is fine as it is).
