Option /pffg is mentioned in the output of "vec -help"
The help text just says "features from GENERAL. Works
with /PFF".
I guess this means that when the flat form is printed
with /pff, the features from GENERAL are normally
excluded unless the /pffg flag is supplied. In that
case, the help text could say "include features from
GENERAL (used with /PFF)".
However, the /pffg flag makes no difference, as can be
seen by piping the output to the word count utility:
[roger@eden kernel]$ vec -pff:integer | wc
446 1641 13423
[roger@eden kernel]$ vec -pff:integer -pffg | wc
446 1641 13423
