Don't skip delays on the campaign intermission screen if a player only presses the button to show the scoreboard.

On the intermission screen, if the player is in a campaign, then they have the option to display the scoreboard over the stats if they press and hold +showscores. However, pressing this button also causes the intermission to skip delays and proceed to the next map, which is kind of annoying if you just want to look at the scoreboard without skipping the intermission. Therefore, if the player only presses +showscores and no other buttons, don't accelerate the intermission.
