12 * This demonstrates/tests cases where check-format.pl should report issues.
13 * Some of the reports are due to sanity checks for proper nesting of comment
14 * delimiters and parenthesis-like symbols, e.g., on unexpected/unclosed braces.
18 * The '@'s after '*' are used for self-tests: they mark lines containing
19 * a single flaw that should be reported. Normally it should be reported
20 * while handling the given line, but in case of delayed checks there is a
21 * following digit indicating the number of reports expected for this line.
