Just to note: we already have this precedent happens with strcasestr()  
function, not covered by standards. Some ports define their own
strcasestr(). We decide to fix ports instead of libc hacking.

And now we have two different ways of handling that case, one for
strcasestr() and another for strlcat(). Where is logic?
