polyglossia \textenglish{} produces extra spaces, while \textspanish{} works properly

Question

I'm working on multilingual documents and noticed that the command \textenglish gets extra spaces in output.

\documentclass{article}
\usepackage{polyglossia}
  \setdefaultlanguage{french}
  \setotherlanguages{english,spanish}
\begin{document}
\noindent \textbf{Résumé:} Et voilà!

\noindent \textenglish{\textbf{Summary:}} Here it is.

\noindent \textspanish{\textbf{Resumen:}} Esto está bien.    
\end{document}

The French and Spanish lines are correct, the English one is not. I'm getting too much space before Summary and before Here, that is, around \textenglish{}. (Of course, Here it is would be marked as English as well, but that's another matter. :-)

I usually work with the memoir class and xelatex.

I tried placing some \ignorespaces, inside or around the \textenglish, but to no avail.

Can anyone help correcting this?

Answer 1

missing % in gloss-english but you can correct it in document:

Note This is already fixed in the sources for the next release.

\documentclass{article}
\usepackage{polyglossia}

  \setdefaultlanguage{french}
  \setotherlanguages{english,spanish}

\makeatletter
\def\english@language{%
   \polyglossia@setup@language@patterns{\english@variant}%egreg's favourite
}%
\makeatother

\begin{document}
\noindent \textbf{Résumé:} Et voilà!

\noindent \textenglish{\textbf{Summary:}} Here it is.

\noindent \textspanish{\textbf{Resumen:}} Esto está bien.    
\end{document}
