Sorry. The other version does this. It's what I intented.

'src' null-terminates and 'target' doesn't, so the loop breaks. If it
didn't break it would enter another iteration and the pointer would
increment after comparison going to address beyond the address of null-
termination. So, it just prevents this. My change is partial and
doesn't do what I actually wanted to do.
