`brew fetch --force` was a no-op for formula pathnames when that formula
did not exist in Library/Formula, because `brew --cache #{f.name}`
results in an error for that case.

Fix it by always using f.cached_download.

Latest is hardcoded, so we'll have to update as new Xcode's come along.

Schoolboy error.

`svn up` doesn't take url argument; compare `svn help up` to `svn help checkout`
Apparently `svn up` can ignore this argument (not documented), but providing this
argument could confuse code readers into believing that changing the url will
switch the branch. It doesn't; the argument is ignored.

This fix was relayed to me, but I've studied it further before posting.
It is related to the bug where --HEAD installs reuse the wrong cache.
Reading the former code, one might hope that providing a changed URL would
have `svn up` change branches. It doesn't; the url was ignored.

Closes Homebrew/homebrew#7159.

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.

Fixes Homebrew/homebrew#7338.

`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.

Closes Homebrew/homebrew#7254.
Closes Homebrew/homebrew#7276.

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.
