If the return value of strlcpy isn't used, the compiler can optimize the extra inefficiency away. (I don't know if any do, though.) This is similar to how strl

If the return value of strlcpy isn't used, the compiler can optimize the extra inefficiency away. (I don't know if any do, though.) This is similar to how strlen(x)>0 calls get optimized to *x by clang and likely other compilers.
