If we are into bike-shedding :), I'd prefer something like:

-Wnonnull 				  	   (since GCC 4.8)
            Warn about passing a null pointer for arguments marked
            as requiring a non-null value by the nonnull function
            attribute.

perhaps with a smaller font and some color, like the annotations here:

but see below.

The place to add them to the manual is: gcc/doc/invoke.texi

You can also submit a patch that adds just one or two to discuss the format 
first and see what kind of feedback you get. As pointed out here 
https://gcc.gnu.org/wiki/Community (point 10): the only people whose opinion 
matters are the people who can review and approve your patch. Thus, CC the 
documentation co-maintainers: you can find them in the MAINTAINERS file.

Follow: 
https://gcc.gnu.org/wiki/GettingStarted#Basics:_Contributing_to_GCC_in_10_easy_steps 
although most things there are not required for documentation changes. It 
should be obvious which ones, otherwise, please ask.

Cheers,

Manuel.
