displacing pet long worm

Salvage part of an old patch.  Swapping places with any long worm,
even a baby one, always failed with "You stop.  Foo is in the way!"
This lets you swap places with tame baby long worms, and adult ones
if they have no tail (which won't happen unless there are more than
32 long worms on the current level--even if a long worm appears to
be only a head, there is normally a hidden tail segment at the same
location).
