bug#51288: Break date SYNOPSIS into two sections

[Paul Eggert]

Thanks for reporting the problem. It'd be a bit of a pain to implement 
your suggestion exactly since the synopsis is generated automatically. 
However, I installed the attached to try to attack the problem of 
confusion that you reported.

It's been years since I set the date by hand but we might as well be 
clear about it, if only for nostalgia's sake.
