read-or-skip-faces ignores which modes inherit from others

[AvverbioPronome]

ie: if I say:

(text-mode read nil)

I also have to say:

(markdown-mode read nil)

Is this on purpose?

Wcheck mode doesn't know about inheritance. It checks the mode name symbol only.

Alternative way to do

(text-mode read nil)
(markdown-mode read nil)

is this:

((text-mode markdown-mode) read nil)
