rubocop --show-cops isn't updated to match .rubocop.yml

[whatyouhide]

Config

I'm on OSX 10.9.1. rubocop -V gives:

0.18.1 (using Parser 2.1.5, running on ruby 2.0.0 x86_64-darwin13.0.0)

Issue

I have a .rubocop.yml file in a directory, which contains only:

WordArray:
  MinSize: 4

and a file test.rb which contains:

['a', 'b', 'c', 'd', 'e']

When I run rubocop --format offences I get:

1 WordArray

which is fine. When I run rubocop --show-cops however, it says:

WordArray:
  Description: Use %w or %W for arrays of words.
  Enabled: true
  MinSize: 0

Why isn't the output of the --show-cops command updated to match the content of .rubocop.yml regardless of what the output of rubocop -h says for the --show-cops option? Here's a quote from that output

Shows the given cops, or all cops by
default, and their configurations for the
current directory.

@whatyouhide You're right. It shows the default configuration even though the documentation and the specs say that it should be the actual configuration for the directory. I'll see if I can fix it.
