Previously, the newline had to immediately follow abackslash. The current implementation allows whitespace in the formof spaces, horizontal and vertical tabs, and form feeds between thebackslash and the subsequent newline. The preprocessor issues awarning, but treats it as a valid escaped newline and combines the twolines to form a single logical line. This works within comments andtokens, as well as between tokens. Comments are <em>not</em> treated aswhitespace for the purposes of this relaxation, since they have notyet been replaced with spaces. </body></html>⌨️ 快捷键说明
