Bug 2792673: when attempting auto-targeting, if the only monsters in LOS have

the line-of-firing to them blocked by a wall then auto-targetting won't happen
and the cursor/cross-hair will remain on the player.  Give a message in such
circumstances so the player will know why the monster wasn't auto-targetted.
(Might also want to give the same message when doing "target cycle forward" in
examination mode)
