Can I suggest the following change for LaTeX-item-list:

diff --git a/latex.el b/latex.el

       (TeX-insert-macro "item"))

Before, there was no newline when the point was at the beginning of the
line. But it often happens, with auto intending, that point somewhere
in the middle of the line.

I have looked for a function to check if the current line is empty, but
did not find one inside of emacs. Above, I'm using a piece of code from
stackoverflow for current-line-empty-p
