[FR] Extra indentation in (mandatory) arguments of environments

[Denis Bitouzé]

Hi,

IMO, an extra indentation is missing in (mandatory) arguments of
environments. For instance, in the following full indented `.tex` code:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
\NewDocumentCommand{\foo}{
  som
}{}
\begin{tabular}{
  rcl
  }
  &&
\end{tabular}
\end{document}
--8<---------------cut here---------------end--------------->8---

it would be nice for the `tabular` piece of code to be indented as
follows:

\begin{tabular}{
    rcl
  }
  &&
\end{tabular}

WDYT?
