+Subject: [PATCH] fix empty array elements in command arguments
+
+Adjacent spaces caused empty array elements due to how String#split works.
+This change removes those empty array elements without modifying anything else.
+Adjacent spaces sent by players are removed in PlayerConnection, so this change doesn't affect players.
+But it does affect the console, command blocks, Bukkit.dispatchCommand, etc.
