--list-sigs shows the sigs.  --check-sigs goes one step further and
checks the sigs for validity.

In general --check-sigs is going to be slower as there is more work to
do.  Whether it is significant or not depends on a number of factors.
In most cases with 1.4.0, it's not even noticable.  In some cases
(with Elgamal signatures and older GnuPG), it's 20-30 minutes slower.
