[Patch/RFC] Improve (maybe ;) basic_stringbuf::overflow

[Paolo Carlini]

Hi all,

this is an idea I got (also perhaps inspired by Nathan).

It tests ok and definitely spares a copy :)

However, I'm not sure the standard guarantees that
swap exchanges also the capacities: I rely on that
property of v3 basic_string implementation.

In case in fact it doesn't, would be ok to just add a
comment about that??

Paolo.
