Subject: bug#48518: 13.0.11; LaTeX environment C-c C-e on region doesn't indent properly
Date: Wed, 19 May 2021 12:57:15 +0200

Whenever I highlight a region and do C-c C-e of any kind, the result
will not have the text indented correctly, and the closing
"\end{environment}" will also not be indented correctly.  Merely the
"\begin{environment} is indented correctly.

Steps to reproduce:

 1. Install auctex
 2. Open a tex file (in latex-mode)
 3. Start an intented environment, such as a section
 4. Write some text
 5. Highlight that text
 6. Perform LaTeX-environment (C-c C-e) on that highlighted region

Example:

```tex
\documentclass{article}
\begin{document}
Hello.
\begin{section}
  Here is a text.

  With some paragraphs.

  Here is a third paragraph.
\end{section}
\end{document}
```

After the steps:

```tex
\documentclass{article}
\begin{document}
Hello.
\begin{section}
  \begin{environment}
  Here is a text.

  With some paragraphs.

  Here is a third paragraph.
\end{environment}
\end{section}
\end{document}
```

It is easily fixed if I rehighlight the text and press tab (indent
region), but this is tedious.  I should try to debug this myself, or
hotfix this by just writing a hook, but it should be easy to fix, and it
is a good exercise for me, but I am too lazy, sorry.

Best wishes
Berthold Lorke
