bug#20933: 24.5; Ispell *Choices* window truncated

[Nick Helm]

The Ispell *Choices* window cuts off the list of options when a
non-nil default line-spacing is set.

>From emacs -Q:

M-: (setq-default line-spacing 2)

"tyype sume mizspelt wurds"

M-x ipsell-buffer

It looks like the sizing of the *Choices* window does not take the
line-spacing into account and obscures the list of spelling options.
