par: Restore Fortran indentation for verbatim code.

Indentation was lost for terminalv changes.  Code was starting in
Column 1 or 6, not 7.  Restore block indentation to three characters
(some twos had been introduced).
KAPPA: Minor documentation fixes.

Main one was to clarify SQORST's PIXSCALE.  Not sure why this
parameter is LITERAL rather than an array of _DOUBLE, but it confused
a user who could not find the correct syntax.
