Public bug reported:

Ubuntu 20.04 Focal beta (as of 2020-04-04)
nano 4.8-1

What I expect to happen: multi-line paste into nano via kitty pastes
multiple lines.

What happens instead: pasted multi-line text is one line with no line
breaks.

There is a bit of a spat between the developers of kitty (gnome-
terminal:kitty::screen:tmux, basically) and nano about how to do multi-
line pasting.  See e.g.:

* https://savannah.gnu.org/bugs/?58010
* https://lists.gnu.org/archive/html/nano-devel/2020-03/msg00005.html
* https://github.com/kovidgoyal/kitty/issues/994

Without taking sides, the facts are:

* With the current versions in focal (kitty 0.15.0 and nano 4.8), pasting 
multi-line will result in newlines being eaten.
* nano 4.9 introduces a fix (commit 481529e8650d105c3280def764e4917af0cabb49) 
which brings the newline handling more in line with other terminal-aware 
programs (treating raw \n as line break).

Peripherally, nano 4.8 introduced new bracketed paste mode support.
This makes a read of the kitty github issue above harder, since the
issue being reported here is about an incompatibility in bracketed paste
mode between kitty and nano, not pre-bracketed ^J handling.
