And there's a commit that changed strcmp() into strncmp():

commit 4aeb63826e0f9ce817b16abdb1501490307d857c

    Check the entire length of the current argument for the EOF string with -E,
    but don't expect a proper ASCII string to exist right here right now, don't
    use strcmp(3) which checks for a NUL.  As we're still building the argument
    up, the next character might be garbage.  It would probably be just as safe
to
    temporarily write a NUL there, but if we've reached the end of argument
memory
    that might not be the best idea, I think.  It's unclear.

    Doing it this way seems to meet the most with the original intent.

Checking if what's described in bug 85696 is still a problem with strcmp()...
