1017  * while the cursor moves around.  This may require changes in the
1018  * "update_monster()" code to allow "visibility" even if off panel, and
1019  * may require dynamic recalculation of the "temp" grid set.

1021  * Hack -- targeting/observing an "outer border grid" may induce
1022  * problems, so this is not currently allowed.

1026  * move through the "interesting" grids in a sequential manner, or
1027  * can enter "location" mode, and use the direction keys to move one
1028  * grid at a time in any direction.  The "t" (set target) command will
1029  * only target a monster (as opposed to a location) if the monster is
1030  * target_able and the "interesting" mode is being used.
1031  *
1032  * The current grid is described using the "look" method above, and
1033  * a new command may be entered at any time, but note that if the
1034  * "TARGET_LOOK" bit flag is set (or if we are in "location" mode,
1035  * where "space" has no obvious meaning) then "space" will scan
1036  * through the description of the current grid until done, instead
1037  * of immediately jumping to the next "interesting" grid.  This
1038  * allows the "target" command to retain its old semantics.
