Make consistent parsing of boolean options #392 is an old comment on philosophy, but recently see this:
All boolean options are
falseby default, so supplying them will set them totrue, unless the value is eitherfalse,no,0oroff.
And I’m still not sure it’s 100% consistent so I’m kind of careful. GUI also has a pitfall where supplying the option doesn’t set it to true. You have to check it (I believe, or at least some people have tripped over that).
