This should be possible, provided that those text-to-PS
filters have options to explicitly switch on/off
pretty-printing (to allow overriding any option already
included in A2PS_BASIC etc.).

Hm?!

(from template apsfilterrc:)

# override a2ps default options
# defaults:
  ^^^^^^^^  ;-)
#  A2PS_BASIC="--delegate=no -X iso1 -g"
#  A2PS_PAPERSIZE="$PAPERSIZE" (case-corrected)
   ^^^^
   these are the defaults

#A2PS_BASIC='-X iso1'
#don't format troff documents, by Joerg Wunsch <joerg@apsfilter.org>
#A2PS_BASIC='-Eplain'
#A2PS_PAPERSIZE=Letter
#A2PS_PAPERSIZE=A4stylus
 ^^^^
 these are examples

# override the complete a2ps commandline
#A2PS_OPTS='-X iso1 -m --borders=yes --prologue=color
--highlight-level=heavy'
 ^^^^^^^^^
 this is only used when set (and it's unset by default)
