Prevent rewrapping with `\b`

Hi @ewels, rich-click is an awesome package and I love that it’s a drop-in replacement for click. However, I’m running into a small issue with rewrapping. click uses the \b flag to prevent rewrapping for a paragraph, which allows you to preserve newlines in a command’s help. rich-click doesn’t seem to support that flag and removes newlines.

Say you have a command foo:

@click.command()
def foo():
    """This is a command.

    \b
    Examples
        $ foo
        $ foo bar
    """
    return

Here’s the output of foo --help using just click:

With rich-click, the newlines are lost.

Using Markdown instead might be an alternative, but would require rewriting docstrings and would break compatibility with click. Any chance of support being added for \b in rich-click?

Thanks!

I thought I had already responded to this but I don’t see my comment here so I guess not.

The issue I had was that I was using rich-click version 1.3.0, and support for this was released in rich-click version 1.3.1.

Once I updated to rich-click 1.3.1, everything works perfectly, as expected.

Thank you for your help and apologies for not checking that before commenting. This package is seriously awesome! 😄
