The reason for removing the previous regexp from default was because
it makes more inconvenient to retrieve more available values from
the list of default values via M-n. But maybe we could just display
the previous regexp in the prompt and accept it when the user types RET
with the empty string, but don't make it available via M-n, because it is
available via M-p for inserting into the minibuffer for editing.

Alternatively, we could change the occur engine to display all lines for
the "" regexp. This is not useful, but at least can be expected for "".
