Merge pasted preformatted text => code block in the new composer when there is only a space as separator

Feature

I did multiple code blocks just 5 minutes ago. Quite normal way to do in minimum level when giving usage examples.

Just an example 
sudo nano /usr/local/bin/docker-ips

#!/bin/bash
# show IPs of containers/gateways and network ID (short form)

if [ $# -eq 0 ]; then
  containers=$(docker ps -q)
else
  containers=$(docker ps -qf "name=$1")
fi

for cid in $containers; do
  cname=$(docker inspect --format '{{.Name}}' "$cid" | sed 's|/||')
  echo "=== $cname ==="
  docker inspect -f '{{range $net,$v := .NetworkSettings.Networks}}Verkko: {{$net}}
  Kontin IP: {{$v.IPAddress}}
  Gateway:   {{$v.Gateway}}
  VerkkoID:  {{printf "%.12s" $v.NetworkID}}{{"\n"}}{{end}}' "$cid"
done

sudo chmod +x /usr/local/bin/docker-ips

I don’t use rich editor anywhere but in my phone, but normally we can’t get empty lines without <br> so then there should be meaningless text :thinking:
