I wish to test the availability of --guesswork by trying the argument and checking the exit status but unfortunately pod2text works differently than pod2man:
% pod2man --help > /dev/null
% echo $?
0
% pod2text --help > /dev/null
% echo $?
1
So if I add --guesswork=none, I cannot distinguish the availability of it with pod2text.
Seems like I should better use for the test:
echo "=head1 test" | pod2text --guesswork=none > /dev/null
And that's what I'll do. However, homogenizing exit status (either to 0 or 1) would be great.
