Get two longtables with the same width

[maieul]

On https://tex.stackexchange.com/questions/63535/align-columns-in-multiple-tables/63544#63544 you show us a solution to get two longtables with the same width.

1. Should it be possible to include this feature directly in longtable.
2. Should it be possible to make it compatible with arydshln?

For the point 2, cf this problematic MWE.

\documentclass[]{article}
\usepackage[margin=0.5cm,landscape,a4paper]{geometry}
\usepackage{longtable}

\usepackage{arydshln}
\makeatletter
\def\dontchopLT{\let\LT@entry@chop\relax}
\def\resumeLT{%
\let\zzz\stepcounter
\def\yyy{LT@tables}
\def\stepcounter##1{%
  \def\xxx{##1}%
  \ifx\xxx\yyy\else\zzz{##1}\fi}}
\makeatother

\begin{document}
\centering

{\dontchopLT
\begin{longtable}{|c|c*{26}{|c}|}
  \hline
  ms&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s\\
  \hline
\end{longtable}}

{\resumeLT
\begin{longtable}{|c|c*{26}{|c}|}
  \hline
  ms&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s&s\\
  \hline
\end{longtable}}

\end{document}

Thanks I'll add to the (growing!) list of feature requests.
