The binding is not mode specific, it's defined in the `global-map'.
With other words, there are no different `comment-dwim' commands for
every major mode, there is only one general `comment-dwim' working for
all correctly defined major modes.

C-h m describes only mode specific bindings; that's why the binding
doesn't show up there.
