Can we support CR line endings as well as LF and CRLF? #35797
Description
VSCode supports LF line endings, and CRLF line endings, but it doesn't support CR line endings.
Any chance of support for this? There are some exotic platforms which still require them, such as e.g. pre OSX MacOS, and the amount of work involved ought to be trivial. This is ff=mac mode in vim.
I've tried manually setting files.eol to "\r", but the value is rejected as being invalid.
Right now, if you try to open a CR file in VSCode it gets normalised to CRLF, which is incorrect. At the very least stopping this from happening would be nice.
