varioref: Get rid of the trailing space if \reftextfaceafter (and friends) is made empty

[dbitouze]

Brief outline of the enhancement

It would be nice for varioref to get rid of the trailing space if \reftextfaceafter (and friends) is made empty.

Minimal example showing the current behaviour

\RequirePackage{latexbug}
\documentclass[twoside]{article}
\usepackage{varioref}
\usepackage{lipsum}

\begin{document}
\lipsum[1-6]

\textbf{See figure~\vref{myfigure}.}

\def\reftextfaceafter {}

\textbf{See figure~\vref{myfigure}.}

\lipsum[1-6]

\begin{figure}[ht]
  \centering
  \caption{This is a figure}
  \label{myfigure}
\end{figure}
\end{document}

I think it is a bit pointless to use varioref and then set the varying part to empty, why would you want to do that?
Besides, if you want to support that for \reftextafter you would need to do that for each and every other \reftext... variable which means a lot of testing on each occation without much benefit.

What I'm prepared to do is, I guess, to document that instead of empty you need to get rid of that space by doing

\def\reftextfaceafter {\unskip}

Sorry, I should have explained the context: I want to do that because an editor requires the class I'm creating for him to not display the reference text for the references that are visible on the current double page. So I need to make empty \reftextfaceafter, \reftextfacebefore, \reftextcurrent (and only them).

\def\reftextfaceafter {\unskip}

does the trick: thanks!
