Help output is missing newlines

[untitaker]

Since the move from clap to argh, the help output for dump-paragraphs and other commands is missing newlines entirely: hyperlink help dump-paragraphs

Usage: hyperlink dump-paragraphs --file <file>

Dump out internal data for markdown or html file. This is mostly useful to figure out why a source file is not properly matched up with its target html file. NOTE: This is a tool for debugging and development. Usage:    vimdiff <(hyperlink dump-paragraphs src/foo.md) <(hyperlink dump-paragraphs public/foo.html) Each line on the left represents a Markdown paragraph. Each line on the right represents a HTML paragraph. If there are minor formatting differences in two lines that are supposed to match, you found the issue that needs fixing in `src/paragraph.rs`. There may also be entire lines missing from either side, in which case the logic for detecting paragraphs needs adjustment, either in `src/markdown.rs` or `src/html.rs`. Note that the output for HTML omits paragraphs that do not have links, while for Markdown all paragraphs are dumped.

There are some upstream PRs in argh that went nowhere.
