Assaulting a foreign sector with nothing but spies is special: the spies sneak ashore. It is, however, more special than it should be: the spies use no mobility and ignore landmines. They do use mobility and hit landmines in other assaults. Assaulting your own sector with nothing but spies is more costly and more risky than assaulting a foreign one. This makes no sense. Has been that way since spies were added in 4.0.0. It's that way because sneaking ashore uses its own code to move the spies instead of move_in_land() via att_move_in_off(). It can't use move_in_land(), because that prints an unwanted "now occupies" message, and destroys the list of assaulting units, which we still need to catch and shoot spies. Factor the code to move attacking land units to the target sector out of move_in_land() into att_move_land(), and use that for sneaking ashore. This makes the spies use mobility and hit landmines even when they sneak. Signed-off-by: Markus Armbruster <armbru@pond.sub.org>
