This avoids the hard-coded string offsets by using strlen. It's a bit of a strange coding style.
Mainly I was interested to see if gcc could optimize this, and (gcc-4.9.2 / x86-64 / -O2) it did - all calls to strlen are removed from the assembly and replaced by constants. When I compile systemd normally, it recommends using -O0 so of course no optimization is done and all the calls to strlen are still there.
