Subject: Parse and ignore the escape sequences \, and \/ (italic corrections).
 Actually using these is very stupid because they are groff extensions and
 other roff(7) implementations typically print unintended characters at the
 places where they are used. Nevertheless, some manuals contain them, for
 example ocserv(8). Problem reported by Kurt Jaeger <pi at FreeBSD>.
