Perhaps the glibc manual could say that although this part of the 
behavior of strncmp/strnlen (and presumably related functions) are as 
stated for glibc and for all other known C library implementations, they 
might be an extension to the C and/or POSIX standards, as opinions 
differ as to whether the standards are clear about this.
