fix bz265 - accessibility fix for reluctant pet

Requested by a blind player.  The message "Fido moves only reluctantly"
didn't convey enough information to be useful.  Describe the reason why
the move is reluctant:  "Fido steps reluctantly over <some object>."

If there is a pile, it will describe the top item rather than whichever
cursed item the pet doesn't want to step on.
