hyperref and \verb

[David Carlisle]

verb can not possibly work in an argument (but the error isn't always
trapped) the font change to monospace can of course work but the
actual verbatim action of making characters like \ or & safe can not
work as they have already been scanned by the outer command, So even
if it failed to give an error message it would just be doing
`\texttt{...}` not showing verbatim tex markup in a safe way.
