add '.'.

Done.

How about:

buffer.append(i->first.begin(), i->first.end());
buffer.push_back('=');
buffer.append(i->second.begin(), i->second.end());

Avoids a few temporaries. I would also .append("; ") rather than +=. Perhaps
there is an optimization that makes them equivalent, but I'm not aware of it.

Done.
