Rationale: everyone thinks it points to the currently installed prefix, not the prefix of the formula that is newest and maybe not installed.
The previous behavior was unintentional and evidence proves it is not intuitive either.
I anticipate no regressions. And hope I am right!
The problem is not the raw URLs, but URLs that do not contain the commit
hash corresponding to a particular version of the gist.

Rather than build the whole output in a string, print each item as we
go. This gives the illusion of improved responsiveness by delaying the
expensive method calls until after the faster output.

FixesHomebrew/homebrew#14554.
We justify doing this because pre 10.8 X11 came with GL for all Homebrew-capable systems and as such is a default that we'd prefer not to have to address.
Checking the license text is probably the most future proofed method. Though for future reference other possible methods are listed in the below ticket.
ClosesHomebrew/homebrew#14558.
This is safe, I tested various scenarios, including Homebrew installed in ~. The only files that are removed are unexpected files in Homebrew's already managed directories.
Two wrapper scripts that find git and svn using the ENV variables we support and then searching through the PATH and looking inside Xcode.app if necessary.
Now just calling git or svn in Homebrew code will find and exec the right tool and we can stop fussing.
Apologies to @adamv who is probably unimpressed that the cmds directory has non-commands in it now. If it's consolation these are temporary pending some more work on superenv whereby some more directories are created under the superenv root.
1. A minimal build environment, we don't set CFLAGS, CPPFLAGS, LDFLAGS, etc. the rationale being, the less that is set, the less variables we are introducing that can break builds.
2. A set of scripts that replace cc, ld, etc. and inject the -I, -L, etc. flags we need into the args passed to the build-tools.
Because we now have complete control over compiler instantiations we do a variety of clean-up tasks, like removing bad flags, enforcing universal builds and ensuring makefiles don't try to change the order of library and include paths from ones that work to ones that don't.
The previous ENV-system is still available when --env=std is specified.
superenv applies to Xcode >= 4.3 only currently.
Similar to the LinkedKegs record, we write a symlink for installed kegs to PREFIX/opt.
Unlike the linked-keg record, unlinking doesn't remove the link, only uninstalling, and keg-only formula have a record too.
The reason for this addition is so that formula that depend on keg-only formula can build against the opt directory and not the cellar keg. Thus surviving upgrades.
To enforce this fix_install_names and built were adapted to use the opt path.
Standard kegs also create an opt symlink so that caveats can now refer to the opt directory and thus provide steps that survive upgrades too.
Thus the choice of /opt. It is short, neat and the right choice: POSIX dictates that opt is for stand-alone prefixes of software.
The == comparison was comparing the versions rather than directly
comparing the strings, which lead to false positives.
