Because restoring frames on tty fails without this fix.

These values are not arbitrary.  The function frame-monitor-attributes
used in the same fixed function frameset-move-onscreen returns on tty:

  ((geometry 0 0 80 23)
   (workarea 0 0 80 23))

where 'left' and 'top' values are zero.

Adding a comment to the source code will help.
