Hi.

This diff adds a non-interactive mode to sysmerge.
It may be handy when updating several boxen (or one even) as it will
save differing files so you can diff/merge them later yourself after
further inspection.
Also yesno was only used once so nuke it.

Man page bits enhancements from jmc@.
Comments?
