Here's a copy-pasted terminal session involving different fish_right_prompts' effects on text selection. Highlight the entire code block and observe that the prompt line has a ton of trailing whitespace, depending on the value of fish_right_prompt.

This trailing whitespace is really bothersome when copy/pasting from the terminal into, say... GitHub issue descriptions!
Either we should delete the printf " " entirely, or make it conditional on nix-shell-info outputting something.
