Markdown Guide should encourage CommonMark standard for links with spaces #454
Description
The CommonMark specification added support for link destinations with spaces as far back as v0.29 (2019-04-06) when the link was enclosed in < and >. The current markdown guide included in the library has a strong opinion about always using %20 for encoding spaces in the section on relative paths. While this works it is sub-optimal. The rendered page will show the %20 when you hover over a link without a link title. If we instead wrap those urls with angle brackets (<url or path here>), then spaces in the url/path will work properly. This also means that when editing the markdown files in an editor or IDE, the relative links will resolve properly as well.
I'm willing to submit a PR fixing this, I just wanted to open an issue to potentially discuss changing the markdown guide first.
