# What counts as wrong is anything PHP says went wrong, anything a
# database says it could not do, and the words the test runner and the
# daemons use when they fail. A line that merely names one of these
# words while reporting a case, such as a case with "error" in its name,
# is left alone: only lines that read as a report of trouble count.
