While GitHub allows a single space to denote a sublist, Jekyll is not
so lenient. It also seems unable to handle ordered sublists.

Add `#installed_caskfile` method to `Cask` class.

Use `CaskLoader.load_from_file` in `Auditor`.

keg: Skip relocation when dylib ID/install name doesn't change.

update: stop autoupdate skipping no formula taps.

Change instances of caskroom.io to caskroom.github.io

Migrate legacy Caskroom.

This will be slightly slower if you have a bunch of non-formula (i.e.
command or cask) taps but it avoids the confusion of having Homebrew
saying it's updated when it only did so selectively.

Fixes #1946.

Remove old metadata when installing with `--force`.

Replace `#plural` by `Formatter::pluralize`.

docs: update Brew Test Bot screen shots

hardware: use march=native for generic module.

test: fix tests with a shallow clone.

java_requirement.rb: use HTTPS in Java Platform URL

Fix “Hombrew” typo.

Fix `uninstall :pkgutil` leaving empty `.app` directories.

It's redirected to cleartext, though this URL will be opened
in a browser so it won't be something hidden, and maybe
Oracle will fix this in the future.

`ENV.prepend_path "PATH", which("emacs").dirname` in the emacs
requirement was causing us to end up invoking /usr/bin/clang instead
of /usr/local/Homebrew/Library/Homebrew/shims/super/clang.

This matches Linux where this behaviour was original imported from.

Refactor artifacts.

Python requirements: Remove casks

linux: Add ARM to CPU.type

Neither python nor python3 are available from Caskroom.

super/cc: Fix --cc=llvm_clang invoked as clang

In this case `HOMEBREW_VERSION` is `>1.1.0 (no git repository)` so these
tests failed. This was the cause of the Homebrew/homebrew-test-bot
Linux CI failures as it was testing a shallow clone.
