The output of `cat <file_name>` is not suffixed with newline causing the prompt string to be appended to the output of `cat`

This is expected when the file has no EOL; bash does the same thing. However, we can do better.

I think this will be part of support for per-command destination-aware output formatting. I haven't settled on the design for this yet but it's on the Trello board.

If the file has no EOL the format I'm imagining is coloured text below reading / No newline at end of file
