Yes, that does include the limits in S2.2.4.1 so a program with
more that 509 characters in a string literal is not strictly
conforming (and that blows away my entry in the Portable Self
Replicating C Code Contest - I forgot about that limit).  As to
whether to count the null or not, it isn't clear, but I don't
think so.  In S3.1.4 it says that "In translation phase 7, a byte
or code of value zero is appended to each multibyte character
sequence that results from a string literal or literals." which
implies that it is no longer a string literal by the time the
null is added.
