I don't understand what you mean by "more accurate".

Here's a snippet that's a bit shorter than yours and doesn't copy the data:

     while (s.length > 0 && s[$ - 1] == '\0')
     {
         s = s[0 .. $ - 1];
     }
     return s;

But do you really want to allow embedded '\0's? I.e., should 
foo("foo\0bar\0") really resolve to "foo\0bar" and not "foo"?

Usually, it's the first '\0' that signals the end of a string. In that 
case you better start the search at the front and stop at the first hit.
