Formulae from the "brewkit" era are no longer compatible with the
Formula class.

This file was (unintentionally) removed from the $LOAD_PATH quite
a while ago, and nobody has complained, so remove it.

This reverts commit ace78b1f3a59a893c7068e485555acf792470080.

Fixes Homebrew/homebrew#30154.

This change removes the cloudfoundry-cli formula from the repository.
It will now be available from pivotal/tap tap.

Closes Homebrew/homebrew#30105.

Some tool involved in `brew install node` is emitting UTF-8 even though
LANG and LC_ALL are unset. Since the external encoding is US-ASCII, we
need to guard against bad data here.

As far as I can tell these methods have only ever been used in the test
suite.

Since Formula includes FileUtils, it is generally simpler (and in the
case of cp, more readable) to use the FileUtils methods directly.

Closes Homebrew/homebrew#30081.

Ruby 2.2 will define Pathname#/ as a simple alias of Pathname#+.
In practice, this means that it will raise a TypeError unless the
argument responds to to_path or to_str.

Currently we blindly convert the argument to a string using to_s, so
deprecate this in the interest of matching the upstream behavior. In the
future we can replace this with

  alias_method :/, :+ unless method_defined?(:/)

Closes Homebrew/homebrew#30079.
