Several issues have been caused by conflicts between the options
Homebrew passes to curl and those read from $HOME/.curlrc. Passing '-q'
will force curl to ignore settings in that file.

Suggested in Homebrew/homebrew#9027.

When investigating issues, one might want to see exactly what curl is
doing behind the scenes. Setting HOMEBREW_CURL_VERBOSE will cause the
'--verbose' flag to be passed to all invocations of curl.

Suggest trying `--use-clang` instead of `--use-gcc` (which does nothing).

The ARGV filtering would strip `--HEAD` from dependency installations,
then proceed with trying to install the dependency from the latest
version in the formula. This causes an error if the latest version is
already installed, so check to see if formula is installed before
performing the installation.

For consistency, ensure that the `path` member of formula objects is always a
`Pathname`.

Gah. This was supposed to be in the last commit, but I forgot to `--amend` it.

Unless the `--quieter` flag is passed.

Closes Homebrew/homebrew#8723.

Unless the dependency is explicitly passed to `brew install --devel`.

Previously, stripping arguments like `--HEAD` for dependencies failed because
that flag affects the installation prefix encoded into formula objects. The
previous implementation of `ARGV` filtering tried to contain all changes to a
single method call before the `FormulaInstaller` forks. This update spreads
things out a bit:

  - The Homebrew `ARGV` extension adds a new method, `filter_for_dependencies`
    which strips flags like `--HEAD`, yields to a block, then restores the
    original contents of ARGV.

  - The `explicitly_requested?` test, which returns true or false depending on
    if a formula object is a member of `ARGV.formulae`, is now a method of
    `Formula` objects.

  - `FormulaInstaller` objects now execute the installation of dependencies
    inside an `ARGV.filter_for_dependencies` block if the dependency was
    `explicitly_requested?`.

This ended up being noise for some users. We need a better set of steps

Git checkouts that do not specify a branch should always reset to the

Homebrew was attempting to check the version of gcc-4.0 and gcc-4.2 even
if they don't exist, causing `doctor` and `--config` to throw nasty
errors.

Also fixes the broken missing gcc-4.2 detection, which was confusing
Xcode 4.2 users.

The recommended compiler versions printed from `brew-config` are out
of date and misleading. The recommendation is always "Run the latest
version of Xcode available for your platform".

Xcode 3.2.6's build of clang is 77, which wasn't being matched by the
clang_build_version regexp.

For GCC and LLVM-GCC, '-v' is not a synonym for --version. When run
without any other options or arguments, it gives similar output, but it
is better to just parse the (terser) --version output.

Using `f.installed?` instead of `f.prefix.exist?` ensures something was created
by the installation step before the install receipt is written.
