IMO this function should act as much like PQescapeStringConn as possible.
Random differences like including or not including outer quotes don't
make the user's life better.  Random differences like a slightly
different rule for the amount of space required are outright dangerous.

Also, why is this patch changing the documentation of PQescapeStringConn?
It might be only whitespace changes, but I don't particularly wish to
have to determine that.
