When writing plain-text files with collaborators, such as…
- #LaTeX, for instance on #Overleaf
- #reStructuredText, for instance for use with Sphinx/for @readthedocs
- #Markdown for many purposes.
…a practice I find very helpful is to:
1. Start every sentence on a new line, and
2. Not hard-wrap within sentences.
This makes it MUCH easier to read ordinary diffs and interpret the addition/removal/reordering of sentences, words, paragraphs, etc.
