I tried to fix that to add the null terminator, but as a result both
push_backs were entirely optimized away.

The Append case is how I think this code should be written. Character by
character loops are only useful as a worst-case estimate; if there's a
performance problem there, you'd rewrite the loop to not push_back
characters one by one, not try to make it go faster.
