@auvipy I presume Eric is using emacs, the double spaces are fine and conform to many technical writing style guides IIRC. You will find many occurrences throughout out the docs.

Interesting! Didn’t know that to be honest

Using double space between sentences is fairly standard. Traditionally the practice was meant to introduce a stronger visual separation between sentences, to help readers identify the boundary. Using a single space is a relatively recent practice, one that reflects an assumption that the software which renders (lays out) the text, like a browser, will render the inter-sentence boundary sufficiently distinctly. However, in my experience that isn't what actually happens most of the time. (Plus, the same software could just as easily detect the double space and render it how it likes.) Furthermore, text editors in particular don't necessarily follow this practice. For example, I use a fixed-width font in my terminal. Ultimately, any time the the text is rendered naively this way, it presents a readability challenge. Thus, I avoid using a single space between sentences.

Traditionally

Very, historically started when type writers where introduced :-)

Unless there are any major objections, I'd like to land this today;, I have a "multiple interpreters HOWTO" branch, on top of this change, that I want to put up for review. If there are little things to tweak, I think we can take care of that in a follow-up PR.
