crecord: drop the extra confirmation screen

The commit confirmation is not very useful -- it gives no way to view what you
have selected, so you're blindly choosing whether to proceed or not, and it adds
a lot of unnecessary friction to committing. In addition, we now have a working
'review' choice for those who really want to review the final change.

Ryan McElroy initially submitted a config option to make this optional, but we
never saw a V2. However as the freeze is near and curses have never been
officially out of the door, I think it is worth skipping the config and trying
getting it right for this release.
