Doing

    (require 'tex-mode)
    C-h f tex-font-lock-verb

shows

    Place syntax table properties on the ^Kerb construct.

where I expected to see \verb.  Perhaps the backslash should be escaped

  "Place syntax table properties on the \\=\\verb construct.

Thanks, fixed.

There is no need for \= though, since \v isn't special to
substitute-command-keys.

Would it be prudent to protect against potential new kinds of \
expansions?  Or anything new would not be alphabeticals?

(I pondered even a checkdoc.el test which could ask for no backslashing
except the defined key seq etc forms.  Leaving room for new kinds of
expansions in the future could be good, but maybe they would never be
alnums.)
