Thanks for the confirmation.

So, I did go away to do this, looked once again at the sigaction.2
page (please pull the latest version), and concluded that everything
in your original patch really is covered in sigaction.2. (SIGTRAP
wasn't covered, but is now.) I really can't see a benefit of adding a
tabular summary to sigaction.2, so I decided not to do this. (Sorry!)

Cheers,

Michael
