- mistie-pop-frameprocedure
This Mistie procedure exits the frame entered by the most recent call to mistie-push-frame, causing the older definitions to take effect again.
In this case, we create a shadowing mistie-def-char for newline, so that it will emit <br> instead of performing its default action (which, as we described above, was to look for paragraph separation). We also define a control sequence endobeylines which will pop the frame pushed by obeylines. With this definition in place, any text sandwiched between \obeylines and \endobeylines (assuming \ is the escape character) will be output with a <br> at the end of each of its lines.
