Insert line breaks in two places in SQL functions documentation.
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.
