Keg#link would sometimes count a linked file when doing mkpath, even if
the target directory already exists; #unlink would never count it. This
meant that "brew ln" and "brew unlink" counts for the same keg could be
out of sync with each other.
`brew link` can now be made to delete any conflicting files using
the --force argument. It also has a --dry-run option, similar to
git clean -n, which will list any files which would be deleted
without touching the filesystem.

Pathname is one of the basic building block classes in Homebrew, and as
such it is preferrable that `require`ing it does not drag in other
Homebrew code; thus avoiding circular dependency situations. Its
dependency on bottles.rb gave it an implicit dependency on formula.rb,
among other things.

file(1) does not allow leading whitespace on shebang lines, and there
appears to be no restrictions on what characters follow '#!', either.
While at it, fix an erroneous shebang test.

The MachO module contains methods for learning about Mach-O binaries,
and can be used where one might normally shell out to file(1).

Rationale: we warn when inreplace makes no changes; this is a similar
sort of warning. We expected some list (probably via Dir) to include
some files, but none were found.
Either the list was wrong, or the install can now be omitted.

The system ln no longer outputs anything. Though the user can force its output with a --verbose of course. So in cases where it's not the usual of: not writable or existing file, we can ask the user to run with --verbose. I don't particularly like hiding its output, but it just confused the error IMO since it is creating a relative symlink the output was weird every time I've seen it in tickets.
I made a print wrapper so that the brew-link output doesn't get mucked up if an exception is thrown.
Rationale: Let's not have duplicate-names. Insisting on only one directory lets the filesystem enforce this unique-naming criteria for us.
We special-case adamv/alt for now, until we remove it.
Rationale: well, it should always have been like this!
However now we are opening ourselves up to more-mixed installations of formula not maintained by us, it's important that
These now return an Array of all the target destinations.
Previously, if a single argument was passed a single non-
Array was returned.
This behavior has been changed so that an Array is always returned
even for a single argument.
Updated the test.
Hopefully this won't break any custom code out there.
If HOMEBREW_KEEP_INFO environment variable is set:
- Do not symlink the info directory file (aka 'share/info/dir')
otherwise it gets overwritten by next installed brew.
- Install an entry in the directory for each linked info file when the
brew is linked.
- Uninstall the entry when the brew is unlinked.

Rationale: some software (e.g. GNU Coreutils, GnuTLS 3.x), have started
distributing _only_ xz-compressed tarballs. There is no system XZ
utility provided by OS X, but it is necessary so that we can continue to
provide formulae for this software.
If XZUtils isn't installed, we abort and prompt the user to `brew
install xz`.
The `xz` command itself doesn't do any untarring, so we write the
decompressed archive to stdout and pipe it to tar.
Commit 2695821e98 ("Only use the bottle if its version is up-to-date")
essentially broke the ImageMagick bottle, because the version parsing
logic returns "1" as the bottle version.
Fixing this requires only a slight modification to the bottle URL regex;
includes a test.
