#249 --plus3-detect-speedlock option is not documented

[Philip Kendall]

The --plus3-detect-speedlock command-line option is not documented

[Fredrick Meunier]

This option is documented since [r4114] so I think this can be closed:

   −−plus3−detect−speedlock
          Specify  whether the +3 drives try to detect Speedlock protected
          disks, and emulate ‘weak’ sectors.  If the disk image file (EDSK
          or  UDI)  contains weak sector data, than Speedlock detection is
          automatically omitted.  See also the  WEAK  DISK  DATA  section.
          Same as the Disk Options dialog’s +3 Detect Speedlock option.

          +3 Detect Speedlock
                 Specify whether the +3 drives  try  to  detect  Speedlock
                 protected disks, and emulate ‘weak’ sectors.  If the disk
                 image file (EDSK or UDI) contains weak sector data,  than
                 Speedlock  detection  is automatically omitted.  See also
                 the WEAK DISK DATA section.
