Which, in turn, provides them for `brew info --json=v1` so other tools
such as e.g. `brew bundle` can make use of this information.

These are used to determine whether or not a formula’s install was
specifically requested by a user and/or pulled in as a dependency.

integration_command_test_case: improve fail output

Instead of `puts`ing when the failure occurs save it until the error
message and print a prose description of what the failure was and the
output from the command. This makes the output from failing tests
significantly easier to read.

bottle: add: improve regexp to recognize comments

audit: only warn on versioned conflicts_with.

uses: properly handle untapped formulae in recursive dependency expansion (again!)

uses: fix recursive requirement resolution

Rather than all versioned formulae regardless. Oops.

This would have eliminated the need for Homebrew/homebrew-core#9000, for
instance.

Add `keg_only :versioned_formula`.

suite_test: skip flaky test.

This is used to indicate a formula is a version of another formula.
This will be used to provide a consistent interface for older formulae
versions and replaces the use of `conflicts_with`.

requirement: get formula from satisfy.

audit: don't allow universal for new formulae.

create: handle null versions.

Unset GREP_OPTIONS.

tests: test Formula#recursive_requirements

This is a temporary measure until:

- #1862 is merged
- I can a test on `brew uses` against every formula in the official
  taps to verify that exceptions are no longer raised.

…rmulae in recursive dependency expansion""

This reverts commit dc9819b8.

Fixes #1848 by sharing recursive dependency resolution between
dependencies and requirements.

Coincidentally, this also fixes the errors introduced by #1784 that
necessitated it being reverted in #1797.

Users may have this set, breaking grep's output.

Fixes #1430.

clarify what should be in brew create url

Fixes #1821

New feature: Allow download from private GitHub repository

When a Requirement is converted to a Formula it should be listed under
the runtime dependencies.

brew.1: use uninstall instead of remove.

Fix documentation for HEAD upgrades.

formula_installer: set specified_path on pour.

This means that a `brew install $ALIAS` records the path accordingly
so  e.g. `Formula#full_installed_specified_name` returns the correct
path.

We're frowning on these now so may as well turn that into code.

These can now be done with just `brew upgrade`, like other upgrades.

Fixes #1818.

audit: whitelist unstable versions already in core

also allow higher stable versions with the same version prefix
