Remove spacing between "}" and "]"

Fix #564

Remove spacing after "}" when it's map key.

Current

// Missing spacing after "}"
fun main() { map[1 + list.count { it != true }] = 1 }

Patched

// No error
fun main() { map[1 + list.count { it != true }] = 1 }

// Unexpected space after "}"
fun main() { map[1 + list.count { it != true } ] = 1 }
