 Agree with Jan on this one.  If the libc's sprintf does not generate a '(null)'
when passed a null string (which several major OS's will not do), the server
will die at the sprintf, so that is really where any such fix would be needed.

 Checking for a null name is valid.

 Animations are pretty simple - items can have an anim <name> in addition to the
fact - this denotes an animated item, in which the face changes.

 More important here is how something is getting the name 'animated dagger' in
the first place.  The only place animations should come from is the 'animations'
file - if there is code someplace adding in animations, that is just plain
wrong.

 Perhaps  - provided it only works for monsters and not players.  Currently,
monsters already have some other special abilities (learn spells from spellbooks
without using them up), so letting them do this is perhaps OK.  Otherwise, it
would seem that checking the return value of apply_special to see if it worked
or not and do the right thing accordingly.

 Not quite sure what you mean by damage unapplied objects in a golem.  I haven't
looked at the animated weapon code to see exactly what it does however.
