## Overview

Per https://git-scm.com/docs/gitignore#_pattern_format, uses preceding
`/` slashes to indicate directories and files that should only be
matched at the root. Which is all of them.

The Git docs also noted that a trailing `/` makes the pattern only match
directories. Since these are known directory names that won't be swapped
with files accidentally, I took out any trailing `/`s to keep the files
as small as possible.

Aside: Per
https://lore.kernel.org/git/pull.1720.git.git.1715705582609.gitgitgadget@gmail.com,
I'm pretty sure the Git docs have a small typo. But per
https://lore.kernel.org/git/xmqqseyk2hce.fsf@gitster.g I don't know that
it'll get resolved soon.
