pressing "s" for sentry does not work right with multiple units on same spot (migrated from trac, id 578 )

When you have multiple planes selected and press 's' to put them all on sentry, if there are multiple units on the same spot, only the upper units are set on sentry.
Very annoying in the heat of battle ;)
