Otherwise if we've committed to `master` and someone `brew update`s
before we cut the tag then they won't be updated to the latest version.

RuboCop: Style/AccessorMethodName

Update manpage.

Add some missed changes. I'll add a CI check for this at a future point.

test-bot: move to tap.

version: don't let a/b imply alpha/beta.

update.sh: always use stable branch for tags.

Migrate to https://github.com/Homebrew/homebrew-test-bot to be able to
work on this with a different, non-tagged workflow.

brew.sh: change directory for HOMEBREW_VERSION.

This is assumption is broken for at least OpenSSL which makes it a
bad general rule.

As discussed in #1102.

This avoids creating a new branch that’ll never be deleted for each tag
and differentiates between the `master` and `stable` branches.

update.sh: do not restore stable (tag) branch

Cask: Use nested classes and modules.

rubocop: allow hash rockets in taps.

Because `depends_on foo: :bar` looks rubbish.

RuboCop: Fix Style/GuardClause.

Fix RuboCop for Taps.

This stops `-dirty` showing up whenever you aren't in
`HOMEBREW_REPOSITORY`.

Fixes #1108.

version: improve alpha and rc detection (elasticsearch)

Restoring stable branch post-update could lead to unsuspecting users
with homebrew.devcmdrun being stuck forever on an old tag.

Fixes #1111.

test-bot: check homebrew/core style.

Even more RuboCop changes.

test-bot: cleanup etc/var after each build.

diagnostic: make using outdated dev tools fatal

Prevent Accessibility access for macOS >= 10.12

RuboCop changes.
