 I have suggestion allowing unknown fields in a .cabal file, and if they
 are named with X- at front, they will not have warning message, and will
 be ignored if they are not understand.

 It should also do similar thing with sections named with X- at front,
 where, it if it doesn't understand that section, it ignore entire section
 with no warning/error (regardless of field names), but if it can use that
 section, it is still warnings for unknown fields in that section without
 X- at front.
