bug#74056: `LaTeX-insert-item' inserts comment characters if called from inside comment

[Vangelis Evangelou]

Hi Ikumi.

Thanks for your reply.

I suggest to set the customize option `LaTeX-insert-into-comments' to
nil. You will get the expected behavior then.

That is correct. Effectively `LaTeX-newline' calls `newline' if the above is nil. I thought to avoid the middleman and call `newline' directly, but I recognise that there are situations, e.g., editing dtx files, where the current behaviour is desirable. On that note, I wonder whether `LaTeX-insert-into-comments' should be made a buffer-local variable so it is set accordingly in various modes. I know that this can be achieved with `setq-local' so it's not a major issue.

I'd like to confirm your intention. It seems that you are saying that
"When I type M-RET in a line with only whitespace charactares, the \item
shoule be placeed in that line, not the line created anew below that
line."

That is correct.

Best,

Vangelis

I'd say that the default value of t of `LaTeX-insert-into-comments' is
one of the strangest defaults of AUCTeX :-)

It seems that it will be useful in docTeX mode. But I personally agree
that it isn't in most LaTeX documents.

To developers: I propose to change the default value of
`LaTeX-insert-into-comments' to nil. What do you think about it? It is
set to t in docTeX mode anyway.

I'd like to confirm your intention. It seems that you are saying that
"When I type M-RET in a line with only whitespace charactares, the \item
shoule be placeed in that line, not the line created anew below that
line." If so, I think it is a reasonable request.
