Source sweep: Replace std::ostringstream when used with a single append

This replaces `std::ostringstream`, when it is written to only once.
If the single written argument was numeric, `std::to_string` is used instead.
Otherwise, the single written argument is used directly instead of the
`std::ostringstream::str()` invocation.
