	 * <p>This method differs from other assertions that effectively only check {@link String#equals(Object)},

	 *
	 * <p>For each pair of expected and actual lines do
	 * <ol>
	 *   <li>check if {@code expected.equals(actual)} - if yes, continue with next pair</li>
	 *   <li>otherwise treat {@code expected} as a regular expression and check via

	 *   <li>otherwise check if {@code expected} line is a fast-forward marker, if yes apply
	 *   fast-forward actual lines accordingly (see below) and goto 1.</li>
	 * </ol>
	 *
	 * <p>A valid fast-forward marker is an expected line that starts and ends with the literal
	 * {@code >>} and contains at least 4 characters. Examples:
	 * <ul>
	 *   <li>{@code >>>>}<br>{@code >> stacktrace >>}<br>{@code >> single line, non Integer.parse()-able comment >>}
	 *   <br>Skip arbitrary number of actual lines, until first matching subsequent expected line is found. Any
	 *   character between the fast-forward literals are discarded.</li>
	 *   <li>{@code ">> 21 >>"}
	 *   <br>Skip strictly 21 lines. If they can't be skipped for any reason, an assertion error is raised.</li>
	 * </ul>
	 *
	 * <p>Example showing all three kinds of expected line formats:
