bug#22390: Spurious backquote in reftex-ref.el

[Arash Esbati]

Hi all,

please consider the following scenario with Reftex enabled:

--8<---------------cut here---------------start------------->8---
\documentclass{article}

\begin{document}
`C-( foo RET' enters \label{sec:foo} and again `C-( foo RET'.
\end{document}
--8<---------------cut here---------------end--------------->8---

Emacs 24.5 works just fine, but the latest Emacs from emacs-25 branch
raises an error:

Lisp error: (wrong-type-argument arrayp (format-message "Label `%s' exists. Use 
anyway? " label))

I tracked it down to a spurious backquote in reftex-ref.el.  Attached
patch is against emacs-25.  Any comments?

Best, Arash
