Pasting into nano strips newlines on macOS

Upon further tests it appears to manifest only inside nano.

What version of nano are you using? https://github.com/wez/wezterm/issues/998 is a similar sounding issue that suggests that installing a newer version of nano may help.

macOS:

nano --version
 GNU nano version 2.0.6 (compiled 14:41:52, Apr 17 2020)
 Email: nano@nano-editor.org    Web: http://www.nano-editor.org/
 Compiled options: --disable-nls --enable-color --enable-extra --enable-multibuffer --enable-nanorc --enable-utf8

remote Debian server via SSH:

nano --version
 GNU nano, version 3.2
 (C) 1999-2011, 2013-2018 Free Software Foundation, Inc.
 (C) 2014-2018 the contributors to nano
 Email: nano@nano-editor.org    Web: https://nano-editor.org/
 Compiled options: --disable-libmagic --disable-wrapping-as-root --enable-utf8

alpine:latest using local Docker on macOS does not manifest any issue:

 docker run -it alpine:latest
/ # nano --version
 GNU nano, version 5.9
 (C) 1999-2011, 2013-2021 Free Software Foundation, Inc.
 (C) 2014-2021 the contributors to nano
 Compiled options: --disable-libmagic --disable-nls --enable-utf8

Even if it works with the latest version of nano, I believe this should be fixed somehow because most people cannot easily update the servers they are managing (think old distros/setups). Before the latest update everything was working fine.

That's fair: I've pushed some changes that allow for canonicalizing to CR characters and made that default behavior on non-Windows platforms. I'll need to evaluate this on Windows as well before figuring out what to do about that.

https://wezfurlong.org/wezterm/config/lua/config/canonicalize_pasted_newlines.html shows the available options in case the default still isn't quite right.

Before the latest update everything was working fine.

The canonicalization behavior hasn't changed in a very long time, so I wonder if there is an additional issue we need to run down here?
