4313f9fe3c PDP1, PDP10, PDP11, ID16, ID32, NOVA, VAX: Open LPT, PTP devices for append
This implements the principle of "least surprise", in that users won't
normally expect to start overwriting an existing file on these devices.
Real hardware didn't behave that way.  A new (empty) file can always
be created with the -N switch on the ATTACH.
