Everything looks fine here. I'm going to commit the patch as-is to
v7-branch, modulo trivial fixes to a few comments and formattings.

Next, I want to add move constructor and move assignment to the sso_base
of string, as per libstdc++/23897 (eventually will go to
vstring/sso_base). Then, as far as I'm concerned, we can essentially
switch to bug-fix mode only for move semantics (besides maybe very few
additional algos?), in preparation for the merge to mainline soon after
4.1 branches. Great!

Paolo.
