Otherwise when `bin/brew` is updated in-place Bash will carry on from
the offset and this can cause issues.
Thanks to `@UniqMartin` for pointing this out.
Everyone should be using a UTF-8 locale nowadays. Not using one causes
issues like `brew doctor` failing while checking symbolic links that
point at file names with non-ASCII characters, since OS X always uses
Unicode for the file system.
Rely on `locale charmap` to detect the currently selected encoding and
if that's not UTF-8, override the user's choice (if any) by setting
`LC_ALL` to `en_US.UTF-8`, the assumption being that every system has a
usable `en_US.UTF-8` locale installed.

For typical installations where `brew` is not a symbolic link, this
reduces the number of processes that need to be spawned.

This reduces the number of processes that need to be forked. If
libtool's `config.guess` is to be trusted, there was never another
spelling/capitalization other that `Darwin`.
This very slightly reduces duplication and the risk of inconsistency by
exporting in one branch, but not the other. By putting all the `export`
statements right before the `exec` it is more obvious what is passed on.
While `var=$(<command>)` is perfectly valid and won't create any issues,
it is often surprising for less shell-savvy users. Quoting these cases
like in all other instances makes the code more uniform, helps to avoid
future mistakes, and has no downsides.
Make it no longer possible to override e.g. `brew install` with a
script if there is already a built-in Homebrew command named
`brew install`.

This allows us to force using the system Ruby on OSX but allow
the development of Homebrew for Linux or Windows to not rely
on OSX paths.

Let's not show weird error messages when user interrupts during various stages of brew initialization.
Tested by doing `for x in $(brew search); do brew install $x; done` and pressing CTRL-C at random short intervals.
Fixes a case where brew would find commands with wrongly-capitalized
user input on case-insensitive systems, then error out with a confusing
message when an invalid method was sent to Homebrew. e.g.:
> brew Update
Error: undefined method `Update' for Homebrew:Module
We don't want bug reports about this crap, even though the user REALLY should listen to the warning message. What actually happens is they blame us instead.
This kind of warning in particular:
warning: Insecure world writable dir /usr/local/bin in PATH
Rationale: some users insist on replacing the /usr/bin/ruby symlink
to point to another ruby on their system, which may break homebrew.
Use the full Framework path instead, which is less likely to be tampered with.
This also reorganizes the brew --config checks to reflect the different path.

'which' only returns a Pathname or nil, and doesn't care about anything
sent to stderr, so just silence it by default and combine the two
methods.

`brew install > file` should not give "export CC=/foo" output on Build Failures.
Also moved the "Using clang" output to brew when BuildError is thrown as that is where it is interesting, and not if you just do `brew --env`.
