Insert line breaks in two places in SQL functions documentation.
This avoids a formatting problem in the PDF output. In the HTML output this isn't necessary, but we've done similar things elsewhere in the documentation so I think it's OK to do it here, too. I've refrained from breaking a longish error message which also causes problems for the PDF output, because that would make the HTML output look wrong. Erik Rijkers
