Are some options also included in --list-properties?

[sharpchen]

I was trying to figure out the difference between options and properties.
The doc says most options are valid properties to mp.get/set_property as well.
I noticed that, --list-properties also includes something not documented in Properties.
Just to make sure, are they valid options as properties? Are those options listed all writeable?

If it is I think it'd better to change this note to mention --list-properties instead

Most options can be set at runtime via properties as well. Just remove the leading -- from the option name. These are not documented below, see OPTIONS instead. Only properties which do not exist as option with the same name, or which have very different behavior from the options are documented below.
