1254  *
1255  * All locations must be on the current panel.  Consider the use of
1256  * "panel_bounds()" to allow "off-panel" targets, perhaps by using
1257  * some form of "scrolling" the map around the cursor.
1258  * That is, consider the possibility of "auto-scrolling" the screen
1259  * while the cursor moves around.  This may require changes in the
1260  * "update_monster()" code to allow "visibility" even if off panel, and
1261  * may require dynamic recalculation of the "temp" grid set.
1262  *
1263  * Hack -- targeting/observing an "outer border grid" may induce
1264  * problems, so this is not currently allowed.
1265  *
1266  * The player can use the direction keys to move among "interesting"
1267  * grids in a heuristic manner, or the "space", "+", and "-" keys to
1268  * move through the "interesting" grids in a sequential manner, or
1269  * can enter "location" mode, and use the direction keys to move one
1270  * grid at a time in any direction.  The "t" (set target) command will
1271  * only target a monster (as opposed to a location) if the monster is
1272  * target_able and the "interesting" mode is being used.
1273  *
1274  * The current grid is described using the "look" method above, and
1275  * a new command may be entered at any time, but note that if the
1276  * "TARGET_LOOK" bit flag is set (or if we are in "location" mode,
1277  * where "space" has no obvious meaning) then "space" will scan
1278  * through the description of the current grid until done, instead
1279  * of immediately jumping to the next "interesting" grid.  This
1280  * allows the "target" command to retain its old semantics.
1281  *
1282  * The "*", "+", and "-" keys may always be used to jump immediately
1283  * to the next (or previous) interesting grid, in the proper mode.
1284  *
1285  * The "return" key may always be used to scan through a complete
1286  * grid description (forever).
1287  *
1288  * This command will cancel any old target, even if used from
