 Fix #1476 by making splice patterns work.

 Unfortunately, splice patterns in brackets still do not work
 because we don't run splices in brackets. Without running a pattern
 splice, we can't know what variables it binds, so we're stuck.

 This is still a substantial improvement, and it may be the best
 we can do. Still must document new behavior.
