In this case, "commit and don't forget to ... later" together with "while 
there isn't such a list, you need to be extra careful about being 
consistent about naming of standards in annotations you add or refine, and 
about what if anything should be listed in @standards in the way of 
information about a function's history beyond which standards supported by 
the glibc headers it's in".
