bug#46117: 12.3.1; windows unfriendly change

Hello Ikumi,

Yes, you are correct in your assumptions regarding my configuration. In fact, I am using straight.el (2nd github link you found). While I agree that this issue is not strictly a bug, it is inconvenient for users who automate the git package pulling process from many repositories (such as straight.el users). If acceptable, I would request that the relaxed coding setting is used (without the "-unix"), especially since the autocrlf setting is very commonly used on windows (default in fact).

To put this case in perspective, I have almost 100 different emacs package repositories that are automatically pulled down using git and this is literally the only emacs lisp file among the complete set that has this issue.

By the way, I have tested on my end and I can confirm that simply removing the "-unix" from the coding and rebuilding resolves any issue.

Thank you,

I assume the following two:
(1) You are using git for windows which enables autocrlf feature.
(2) You built AUCTeX on a local copy of git repository.
(Actually I couldn't reproduce the problem by just copying the files to
my windows 10 and running configure and make with msys. It's only after
a web search with the keywords "local variables entry is missing the
suffix" that I realized what's going on by references such as:
The autocrlf feature silently converts the eol of the files in the
working directory from LF to CRLF, which ends up with contradicting
coding: tag specified in tex-jp.el.

I think that the proper approach for this issue is to turn off the
autocrlf feature for at least the local AUCTeX repository, but at the
same time think that it isn't bad to make AUCTeX more generous to
loosely configured local git repos. I'll remove eol suffix from coding:

I don't think it's windows unfriendly. As stated above, the current tag
coding: iso-2022-jp-unix
works fine even on windows if the file is copied as-is, without eol
format conversion. In my opinion, it's more of the problem on the side
of git for windows, with respect to the status of autocrlf feature.
