Kitty: Line-endings are consumed by kitty when copied to clipboard buffer

Describe the bug

Line-endings are consumed by kitty when copied to buffer

To Reproduce
It is not 100% reproducible, but I usually do git diff on console, and then copy output somewhere... the larger is output, the greater is chance of the bug

I need some way to reproduce, you can run kitty with --dump-bytes,
reproduce the issue minimally (that means in a new kitty instance)
and attach the dump.

[basiliscos]

ok, I'll run with --dump-bytes by default, and as soon as I'll be able to catch it during my work, I'll attach it here.

[kovidgoyal]

Be aware the the dump will contain everything from the session, so dont attach it if your session has anything sensitive in it. It is best to repro the issue with as few steps as possible.

[basiliscos]

thank you for note.

Please, download an sample from

https://send.firefox.com/download/0275739d43dc63ff/#aDt8n_5doyq3HckwQ1DcWQ

(this is one-time link, it will disappear after downloading). Let me know whether it is OK for your.

(I noted buggy behavior on git diff --relative )

[kovidgoyal]

I downloaded it will take a look when I have a moment

[kovidgoyal]

For the record, here is a minimal reproducer from your dump (can be used with

kitty sh -c "kitty --replay-commands repro.txt; read"

repro.txt

[basiliscos]

yep, seems so.
