Add a line between the string and line completion for param name

Prevents errors with here-string completion logic issues

I currently create some completion commands with python. See example here

Using the following syntax

python -c  << EOF
<insert python code here>
EOF

The EOF must be on its own line.

I use a sed hack at the moment to get around this.

Maybe it would be a good idea to only do this if $string consists of more than one line, to not make simple commands more verbose
