Sync OpenBSD patchset 371:

Browse Source 
Add "grouped sessions" which have independent name, options, current window and

windows and so on are mirrored between the sessions). A grouped session may be
created by passing -t to new-session.

Had this around for a while, tested by a couple of people.
