that works great for TAR_ROOM_CHAR and TAR_DOOR_CHAR, but what about
TAR_ROOM_WORLD and TAR_ROOM_MOB.  hmm... i think i have come up something rather
flexible.  Just pass this struct around filling in the required places, and
letting the TAR_* take care of which member is valid.  I am really trying to
avoid manual spells, because I see a lot of these spells coming in.

struct spell_target {
  struct char_data *tch;
  struct obj_data *tobj;
  struct room_direction_data *tdir;
  struct room_data *troom;
  struct someothertarget_data *tother; /* just an example */

and then we just set the targets we need and use the TAR_* flags to determine
which flags are needed.

I coded them as manual spells and used George's idea for spell
arguements. If you'll hit his page of patches, you'll find on there for
spell arguements. When I played with the idea, he had it listed under
"experimental", but should have moved it from there since there.

It worked quite well.

I also did the same thing for the ones that target the room, the few
spells that give the room affects, assume that the target is the room.
There is a "room affects" snippet out there somewhere. I think it's on
Alex's list of snippets. Works pretty well too.
