  coords <buffer> (filename)

  "coords" loads astrometric parameters for the given buffer from the
header of the named file.  The parameters are applied to the buffer,
and will register in the Ki'i window if the buffer it tv'ed again.
This is particularly convenient for intercomparing coordinate system
or in the event the astrometry is stored in a different file (eg, a
stripped off header).  Currently, the only format of coordinate
information that is looked for are gene's linear transformation: RA_O,
RA_X, RA_Y, DEC_O, DEC_X, DEC_Y such that the RA,DEC of an object is
given by:

RA  = RA_O  + x*RA_X  + y*RA_Y
DEC = DEC_O + x*DEC_X + y*DEC_Y.
