Thanks for confirming.  I'm not sure about the intention behind it, but
I think we should if we can fix this issue.

My simple idea was to have an extra check at the end of `texmathp'
itself in terms of: Pass the possible point for math-on to
`LaTeX-verbatim-p' and see what it returs.  I think the possibility for

  $ a \verb|$| $  <= invoke texmathp here

is next to zero while this

  $ a $ \verb|$| <= invoke texmathp here

or this

  \begin{verbatim}
  $
  \begin{end}
  <= invoke texmathp here

are not so far away, from user POV.

I'd say yes: Imagine you want to write a trivial example of bash command
in your document:

  \begin{verbatim}
  $ touch foo
  \begin{end}

currently breaks.
