ArgsBarg 0.2.0

Changed

• Help Notes rendering respects newlines in the source string; indented lines are kept as single rows (shell examples). Built-in completion bash / completion zsh notes use extra blank lines for readability.
• Built-in help Notes for completion bash / completion zsh: plainer wording, short intro lines, then concrete shell examples. completion zsh notes also cover eval "$(…)", source <(…), and file + fpath.
