Document more ways to force a line break

[mtsknn]

This might be too off-topic, but since there's already a "How do I force a line break?" entry in the FAQ, here are some more ways to force a line break.

AsciiDoc

<br /> is not supported.

You can instead use a trailing space followed by a plus (i.e.  +).

Can be verified at https://asciidoclive.com/edit/scratch/1.

Haddock

Couldn't find anything online. I don't have Haskell installed so I can't test this myself.

Markdown

<br /> and trailing spaces are supported as already mentioned in the FAQ entry.

Another way is to use a trailing backslash like this:

lorem\
ipsum

This is supported at least by CommonMark (can be verified at https://spec.commonmark.org/dingus/) and GitHub Flavored Markdown (tested on GitHub).

IMO using a backslash is the cleanest way, though maybe not as obvious as <br />.

MediaWiki

<br /> is supported as mentioned at https://www.mediawiki.org/wiki/Help:Formatting#Paragraphs.

Org mode

<br /> is not supported (tested on GitHub). On the other hand, I don't know how well GitHub supports Org mode.

You can instead use two trailing backslashes (i.e. \\) as mentioned at https://orgmode.org/manual/Paragraphs.html.

reStructuredText

<br /> is not supported (tested on GitHub). Same here that I'm not sure if it's a shortcoming in rST itself or in the rST parser/whatever used by GitHub.

Some methods are mentioned at https://stackoverflow.com/q/51198270/1079869. (None of them are very clean IMO.)

Not at all! Thanks so much for taking such a thorough look at the available options, @mtsknn.

I just opened #7, which incorporates this new information. Beyond any additions or corrections, I'll want to update the CSS to support nested definition lists ahead of merging it.
