Subject: `LaTeX-fill-paragraph` behavior within indented environments

Hi there,

When the point is on the first letter of a line inside an indented environment (e.g., itemize, proof, etc.), running `LaTeX-fill-paragraph` will move the point to the beginning of the line. Here is a MWE:

\documentclass{article}

\begin{document}
\begin{itemize}
\item In indented environments, when the point is at the first letter
    of a line, running ``LaTeX-fill-paragraph'' will move the point to
  the beginning of the line. Ideally, it should stay with the letter.
\end{itemize}
\end{document}

1. If the point is on the first “o” in the line immediately after “\item”, running `LaTeX-fill-paragraph` moves the point to column 0, while “o” is moved to column 2 because of the filling operation.
2. If the point is on the first “f” in the same line as above, the point stays on “f” after running `LaTeX-fill-paragraph` (both moved to column 3).

I think it is better to have consistent point behavior as in scenario 2, because users probably want to continue editing after running `M-q’, and it is much more efficient if the point stays on the same letter before and after filling.

Best,
Ruiyang
