Subject: [PATCH] doc/_ext: check "default" for None

default could be None and we don't reference the default value using
`opt.default`, so this variable is always defined. to avoid printing
a None default value, check for a None value. see
https://jinja.palletsprojects.com/en/2.11.x/templates/#none
