Swaps the value of @first and @second if @second comes before
@first in the buffer. That is, ensures that @first and @second are
in sequence. Most text buffer functions that take a range call this
automatically on your behalf, so there’s no real reason to call it yourself
in those cases. There are some exceptions, such as gtk_text_iter_in_range(),
that expect a pre-sorted range.
