When multiple kegs are installed, `brew info` marks a keg with an
asterisk if f.installed_prefix == keg, but this is only true if either
HEAD or the newest version of the formula is installed. This isn't
always useful, so let's mark the currently linked keg with an asterisk
regardless of the version.
Obviously, keg-only formula will never be marked, but this is probably a
feature. When multiple keg-only kegs exist, chances are that they are
each being utilized by something, so there isn't really a "used" and
"unused" version.

`rack` is a commonly used alias for `formula.prefix.parent`---so common that it
gets defined and used quite a bit. This patch makes `rack` an official method
of the `Formula` class.
The git command now uses --git-dir instead of --work-tree.
Using --work-tree won't work if you are inside another Git repository.

The code was sucking. To the extent that maintenance was hard. It's a lot
easier to work with code that is sensibly split at sensible boundaries. So
now it is more like that.
But the refactor is minimal. Because we don't want you to have more merge
hell than absolutely necessary.
If you merge you will need to pay attention to brew.h.rb (as it is deleted)
and bin/brew (as command logic is gone). It will be painful, but you will just
have to help git out by moving any changes around manually.
Note compatibility.rb. It ensures that any function renames or removals don't
break anything. We're pretty serious about backwards compatibility. And that's
because we encourage you to hack around with the innards. And we couldn't do
that if we would then just make stuff disappear behind your back.
