I was reading the .md file to add a new microproject and found this.
Instead of adding new config case by case, should we do something more
generic?

We could have a new group defaultOptions.<command> (or
<command>.options) which contains <option-name> = <value> where option
names are the long name in parse-options? Then we don't have to
manually add more config options any more (mostly, I'm aware of stuff
like diff options that do not use parse-options).

If we want to stop the users from shooting themselves in the foot, we
could extend parse-options to allow/disallow certain options being
used this way. Hmm?
