Martin, I added several test cases to verify the swap with temporary
string and committed the test:
http://svn.apache.org/viewcvs?rev=406940&view=rev

I plan to enhance the test to exercise the function with unequal
allocators.

With best wishes,
Anton Pevtsov

This is okay for now, btw., please go ahead and commit it. We do need to
enhance the test to exercise the common idiom used to shrink a string
object to 0 capacity:

     {
         std::string s ("...");
         assert (0 < s.capacity ());

         std::string ().swap (s);
         assert (0 == s.capacity ());
     }
     // check for memory leaks

I think the cases might already be there, I'm just not sure
I see where we check the capacity or for memory leaks.

In addition, when UserAlloc is ready for prime time, we need
to remember to enhance the test to exercise the function with unequal
allocators.
