Actually, that was a problem with my transcribing of the docs to
email.  I accidentally removed the backslash.  Oops.  Now:

I did.  It reached the relevant routine as merely `$'.  It looks like
an earlier stage of processing stripped that level of escaping.  I
definitely needed two \\'s to make it work.
