frenchchapters option produces ugly table of contents

[nicolasmeric]

When the frenchchapters option is enabled, the number in the table of contents is also replaced by the ordinal premier written in letters, leading to words overlapping in the table of contents.
Here is a MWE:

\documentclass{report}

\usepackage[frenchchapters]{impnattypo}

\begin{document}

\tableofcontents{}
\chapter{Test}

\end{document}

Interesting. I guess I haven't seen it because I often tune my tocs:

\newcommand{\myshorttoc}{%                                                          
  % Sommaire                                                                        
  \begingroup                                                                       
  \renewcommand{\chapstyle}{\centering}                                             
  \renewcommand{\chapheadstyle}{\chapheadfont\LARGE}                                
  \titlespacing*{\chapter}                                                          
   {0pt}{0em}{4em}                                                                 
  \setlength{\cftchapindent}{-1.5em}                                                
  % Reduce skip between chapter entries                                             
  \setlength{\cftbeforechapskip}{-0.2em}                                            
  \shorttableofcontents{Sommaire}{0}                                                
  \endgroup                                                                         
}

You can keep "Chapitre premier" but change it in TOC and for sections by using:

\renewcommand{\thechapter}{\Roman{chapter}}
\titleformat{\chapter}[display]{\normalfont\huge\bfseries}{
   \ifnum\value{chapter}=1 \chaptertitlename\ premier\ 
   \else \chaptertitlename\ \thechapter
   \fi
}{20pt}{\Huge}

I have open a PR to fix that with the setting romantoc.
