bug#19670: 24.4; pcase-let bug?

> 1 produces (1) and 2 nil. Bug?

Feature: the `pcase' form can have several branches (and defaults to
nil if no branch matches), whereas the `pcase-let' form doesn't have the
luxury of a "default case if it doesn't match", so we have to choose
between "signal an error if it doesn't match" or "pretend it matched".
I opted for the second choice.
