Roughly yes, see the other comment.
On reflection, though, I like the suggestion of returning an
std::pair<std::string, bool>. Make a typedef of that so that users can
declare return-value variables, and use it where it's absolutely
necessary to know that it's not an empty string but a null string. Saves
a lot of trouble with the string subclassing, too. And better than
pulling in 90% of boost just to get a poor-man's replacement for null
references.
