As I was testing several related bugs (PR#29982, PR#39339, PR#39430):
"goto_get_turns: Assertion unit_is_in_focus(punit) failed"
I found that hitting escape caused the list of focused units to disappear.
Clicking anywhere on the map restores the list.
The simple explanation, in client/control.c key_cancel_action(),
set_hover_state(NULL, HOVER_NONE, ACTIVITY_LAST, ORDER_LAST);
update_unit_info_label(hover_units);
set_hover_state() has just set hover_units to NULL. This should actually be
get_units_in_focus(), as they are still in focus.
===
Further checking shows that this is one of only two places that hover_units
is actually used.
In fact, every other call to update_unit_info_label() is passing
get_units_in_focus() or the equivalent pfocus_units. This is the only
exception -- and it's wrong!
(Ignoring the problem that gui-mui still only handles a single unit.)
Obviously, the assert() requires all goto units are in pfocus_units.
There's no explanation for why hover_units exist. It is always either NULL
or identical to pfocus_units. There's no code that changes hover_units to
ever make it any different from pfocus_units.
Does anybody remember? Otherwise, I'm getting rid of it.
