Log Message:
Update to 2.14. From the changelog:

[FIXES]
The -s flag would fail to suppress certain warnings.  Thanks, Kassio
Borges. (GitHub ticket #439)

The -w flag would fail to work properly with regex features such as
alternation.  Thanks to Ed Avis for the report (GitHub ticket #443)

The -g flag should now work faster on larger codebases.  Thanks to
Manuel Meurer for the report (GitHub ticket #458)

More fixes for Windows tests.  Thanks to GitHub user @ispedals.

More whack-a-mole with Windows failures.  This time, it's POSIX::mkfifo
dying on Windows instead of returning undef like the docs implied,
or at least that I inferred.

Fixed incorrect deduping of config files under Windows.  Thanks,
Denis Howe.

More build fixes for Windows.  Windows config finder fixes from
James McCoy.

t/ack-named-pipes.t uses POSIX::mkfifo instead of the external
command, which should be more portable.  Thanks, Pete Krawczyk.

The building of ack-standalone relied on the output of `perldoc
-l`, which I apparently can't rely on having been installed.  I've
changed the way that the squash program finds File::Next.

Issue #313: ack would fail when trying to check files for readability
on some networked filesystems, or on Mac OS X with ACLs.  Now it
uses the filetest pragma.  Thanks, Jonathan Perret.

[ENHANCEMENTS]
ack now ignores JavaScript and CSS source maps.  Thanks, Chris
Rebert.

ack now ships with customized shell completion scripts for bash and zsh.

Add docs for available colors in ack.

--create-ackrc keeps the comments that describe each of the options,
and it shows the ack version number.

Now ignores Cabal (Haskell) sandboxes.  Thanks, Fraser Tweedale.

Added filetypes for Jade, Smarty and Stylus.  Thanks, Raúl Gundín.

[INTERNALS]
ack's entire test suite now runs under Perl's -T taint flag.  We'll
build more security tests on top of this.

Added some checks to the squash program that I hope will turn up
errors in the Windows builds.
