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"?

Whoops. Your code actually turns "foo\0bar" into "foobar", removing the 
embedded '\0'. So my supposed alternative is wrong.

Still, you usually want to stop at the first '\0'.
