Because of this messing with the user's path:

brew uses /usr/bin/git over brewed git, even when the former is
problematically old.
There may also be other reasons a user prefers to use brewed git.
There was already a HOMEBREW_FORCE_BREWED_CURL option and a
HOMEBREW_SYSTEM_CURL_TOO_OLD check to set it. This mostly copies those
to implement HOMEBREW_FORCE_BREWED_GIT & HOMEBREW_SYSTEM_GIT_TOO_OLD.
See also: https://github.com/Linuxbrew/brew/issues/736
Rather than reusing `HOMEBREW_NO_AUTO_UPDATE` to indicate that we've
already made a check. This allows `HOMEBREW_NO_AUTO_UPDATE` to be
displayed properly by `brew config`.
- `brew update` should try to install `curl` before `git` on older
versions of Mac OS X where it is needed for accessing modern SSL
certificates.
- We don't need an HTTP mirror for `git` because `curl` will already be
installed before it is downloaded.
- Don't recommend GCC on Mac OS X versions where it can't be built with
the default system compiler.
- Start using the Homebrew `curl` on Mac OS X versions where it is
needed as soon as it is installed.

Prefer $XDG_CACHE_HOME if defined, falling back to $HOME/.cache.
The Mac cache location is not affected by this change.

If people have `HOMEBREW_RUBY_PATH` set then things explode in a rather
confusing fashion. Instead, run `bundle` for them with the arguments
that they'd want.
Also, move `macho` requires into the module itself; it's a pain having
to do everything for Bundler before requiring `pathname` which is a core
Ruby class.
November 1st 2016 has come and gone so it's time to disable this.
Also, add comments explaining why the things that have been whitelisted
have been (to avoid more being added without good justification).
