Several years ago I started putting every sentence on a new line when I write LaTeX, as it makes diffs cleaner if I want to go back and compare versions of a document.

I do the same but I noticed it feels very weird to write like that, it feels much more staccato, as if there's a bigger pause between each sentence. Nowadays I write paragraphs normally and then split the lines afterwards.

For the most part I do the same when writing emails.

Appears to be a higher chance of people reading them that way.

I don't write a lot of fluff though, and usually have two or three trimming passes before sending.

we’re all conditioned by twitter now, it should be fine! /s

Now that you mention it though i bet there’s an easy macro to do this in emacs ...

I do the same in source documentation, to limit the portion that has to be reformatted when changing something in the middle.

i’d have trouble keeping line length limits in docstrings.

It doesn't mean that a sentence can't contain line breaks. It means that there's a line break after each sentence. This causes paragraph reformatting (for maintaining line length) to be restricted to the current sentence, instead of also affecting the following sentences.
