27c2dfa8f0 All DECtape devices: Undo previous unnecessary change relating to -A switch 
Although these devices interpret a -A switch at attach time, they are not
sequential output devices and thus don't have an ambiguous interpretation
of the switch.

Incorrectly mentioned in #821

614ad52091 All: Fix devices that attach files and have special meaning for -A switch 
The -A attach time switch implicitly means to open files in append
mode.

Some devices used -A to indicate ASCII data or AUTOSIZE of disk or
fixed size tapes - DECtape.  These devices are either read only devices
(Paper tape readers or card readers), so explicit forcing of the attach
to be -R avoids unexpected positioning errors.  The random access
Disk and fixed sized tapes buffer the container contents in memory
so append mode isn't relevant, but care must be taken to assure that
the buffer reading starts at the beginning of the file without regard
to the explicit open mode.

As reported in #821

80d9393b83 alpha, HP2100, ID16, ID32, I7094, PDP11 and VAX: Fix array REG definitions 
Array REGister definitions have been made consistent by passing the
name of the array object.  This allows proper sizing assessment
to occur in the register validation logic.

Some previously described array REGister initializers were not really
arrays.  Some were structures and others were merely pointers to
someplace in memory that it was desirable to view as a scalar array.

Structures or other blob data should now use SAVEDATA.  Virtual
arrays intended to be interpret some part of memory as scalar data
now use VBRDATA initializers.
