errchk: allow multiple patterns // ERROR "pattern1" "pattern2" means that there has to be one or more lines matching pattern1 and then excluding those, there have to be one or more lines matching pattern2. So if you expect two different error messages from a particular line, writing two separate patterns checks that both errors are produced. Also, errchk now flags lines that produce more errors than expected. Before, as long as at least one error matched the pattern, all the others were ignored. Revise tests to expect or silence these additional errors.
