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.

If you want to send me a patch, feel free!

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().
