Subject: 29.1; Remote files lose their coding system & line ending style

[Message part 1 (text/plain, inline)]

I visited a remote file with DOS line endings over SSH, added a line and
saved. The file still has \r\n at every line, but now Emacs reports
"Unix-style LF" as the line-ending style; if I add more text and save
again, the line endings are converted to \n.

Something similar happens with remote files in iso-latin-1. After
saving, they're converted to utf-8-unix. I noticed this in `git diff`: it
reported changes in some non-ASCII text that I hadn't touched, which was
surprising.

Neither problem occurs with local files.

This sounds like bug#65022. Please read the discussion at
https://debbugs.gnu.org/65022, which contains also a patch which you
might try. It will be fixed in the upcoming Emacs 29.2.

Best regards, Michael.
