You for some reason elided the part where I explained why an
Emacs-only solution is unacceptable.

I think you are trying to use features that make no sense in
text-based modes.  Just because the text mentions symbols quoted in
some way doesn't yet mean that text is like a program source.

Maybe we should have separate (sub)commands for when symbols are
mentioned within human-readable text.  Tweaking what a word is due to
this is a too large hammer, IMO.
