New versions of file return `script, ASCII text executable`. Apple may ship the newer version with 10.8 so we may as well be ready for it.

Fixes Homebrew/homebrew#7353.

And fix node and ruby to use LLVM without complaint with Xcode 4.1 and Lion.

CMakeLists.txt is the build instructions not the build logs. The cache is not much better, but there is no equivalent of config.log, so…

I've not been very careful lately, I apologise.

`brew update` was treating all changes to internal commands as
deletions due to a typo, resulting in spurious notifications of removed
commands.

Specify the refspec 'refs/heads/master:refs/remotes/origin/master' so
that the remote-tracking branch origin/master gets update during `brew
update` (git-pull updates remote-tracking branches when invoked
like `git pull` or `git pull origin`, but not `git pull origin master`).

The self help text does not mention the log, but we can add this later, and for now at least the file is salvaged.

Closes Homebrew/homebrew#5940.

Rationale: brew doctor shouldn't give warnings for a default install. And this particular warning only applies for a small subset of formula: the ones that are "dupes".

If we get reported issues that prove this was a mistake we will revert it.

Also tidied error output. Still could be tidied quite a lot but I am still considering how best to go about it.

Now when people search for it or try to install it they will receive a helpful message.

It seems like latest build of Xcode 4.2 doesn't create "-4.2" links in /usr/bin. Because of this recipes fail with "configure: error: C compiler cannot create executables" error.

Amended to work as intended, since /usr/bin/cc is actually since Xcode 4.

Amended commit message. First line must be less than 72 characters! :P

Executing `curl(*patches)` was failing on Leopard when `patches` was an empty
list. `git-bisect` identified 48552bb42a69ece4eb2a6d9acf81a0b47adb19c9 as the
commit that caused this bug to surface by adding `--insecure` to the arg list
on Leopard. This is odd because the following both exit with status 2:

    curl
    curl --insecure

The only apparent difference is that `curl --insecure` prints "no URL
specified!" to stderr along with the usage message.

Also renamed `patches` to `external_patches` as it is more descriptive.

If an integer is passed to `brew-pull`, such as `brew pull 6600`, it will be
interpreted as a pull request number. This has the same effect as the more
verbose command line:

    brew pull https://github.com/mxcl/homebrew/pull/6600

I believe this fixes it though I confess I didn't test. The guy who opened this issue is the expert.

Closes Homebrew/homebrew#7101.

Deprecated use_clang? etc. since the logic was such that multiple states could be set, when in reality only one compiler can be set.

Changed fails_with_llvm handling so if HOMEBREW_USE_LLVM is set then it tries to build even if the formula has fails_with_llvm set. Rationale: mostly they will no longer fail and we need to catch these cases.

Also tidied it up a little, reducing duplication as per original patch.

The SSL certificates on this old version of OS X are outdated and who knows if Apple will fix them.

Fixes Homebrew/homebrew#6103.

Removed updated external commands, like seriously, who cares? We could add it back as if --verbose is set I guess but in all honesty, if nobody complains then nobody cared.

# We removed many redundant comments
Removed many redundant comments.

Fixes Homebrew/homebrew#7191; though it could be fixed better.

Fixes Homebrew/homebrew#7220.

Additionally, add '--build-from-source' to the bash-completion script.

Additionally, document the '--build-from-source' option for the
`install` command.

Rationale: if you edit a formula to use a different source URL it should build that and not the pour the bottle. Obviously.
