Subject: Apply trap door destination restrictions in dodown
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e148d5e92542e98a0742db03ec72379c86c8ae80;p=nethack

Apply trap door destination restrictions in dodown

Missed this way to use the trap door (in a block added in 05761ba) in
previous commits, though I'm a little confused about whether that block
in dodown is even reachable given how various trap scenarios are handled
with dotrap earlier in the function.
