This patch adds verbose descriptions to _cvs.

But I didn't removed -x, -z, etc because cvs-1.10.8 has them.
Although some old cvs may not have them, I didn't tried to check it.

Would you add some version check?

This patch fix some typos in _diff_options.  Although I consider to
use _diff_options from _cvs, I didn't do it because _diff_options
completes some surplus options such as -l, -T, -r, etc.
