I commented the 886 line from latex.el to correct this issue, but
I do not know wether it can have side effects.

       (save-excursion
         (funcall goto-end)
         (let ((old-env (match-string 1)))
           (replace-match environment t t nil 1)
;;l 886     (beginning-of-line 1)
           (funcall goto-begin)
           (replace-match environment t t nil 1)


This issue occurs when I use embedded calc to write a matrix in LaTeX
form.

Thank you for the report. AUCTeX assumes that \begin and \end lie on
their own lines in general, hence the behavior.

Looking at the relevant code, I think I can do something for
LaTeX-modify-environment to cover the situation where \begin and \end
are on the same line. I expect that I can have spare time to manage this
issue on November.

Regards,
Ikumi Keita

I pushed the fix to the git repository. Sorry for delay due to my loose
outlook about my schedule :-)
