OK, I've added it to do-list.htm.
I don't want to try to add it for 1.30.0 - it's too late at this point.

PS: In researching this, I found that the C++ standard seemed to indicate
that basic_string::swap() did not give the expected guarantee not to throw.
I've raised the issue with the committee, as it looks to me like a defect.
Of course, the defect might just be in my expectation for
basic_string::swap().
