FakeFS Dir.glob behaves differently with recursive globs.

[samg]

In the standard lib Dir class the ** recursive glob matches zero or more directories. In FakeFS it matches one or more.

>> File.open('/tmp/in_tmp.txt', 'w')
=> #<File:/tmp/in_tmp.txt>
>> Dir['/tmp/**/*']
=> ["/tmp/in_tmp.txt"]
>> require 'fakefs'
=> true
>> File.open('/tmp/in_tmp.txt', 'w')
=> #<FakeFS::File:0x12165dc @mode="w", @file=(FakeFile name:"in_tmp.txt" parent:"/tmp" size:0), @path="/tmp/in_tmp.txt", @open=true>
>> Dir['/tmp/**/*']
=> []
>> Dir['/tmp/*']
=> ["/tmp/in_tmp.txt"]

The FakeFS behavior should mimic the standard lib.

Actually the fakefs recursive glob (**) behaves exactly like a single wildcard (*) matching exactly one directory, not one or more as stated above.

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'fakefs'
=> true
irb(main):003:0> File.open('/one/two/three/four', 'w')
=> #<FakeFS::File:0x1216564 @mode="w", @file=(FakeFile name:"four" parent:"/one/two/three" size:0), @path="/one/two/three/four", @open=true>
irb(main):005:0> Dir["/*"]
=> ["/one"]
irb(main):006:0> Dir["/**"]
=> ["/one"]
irb(main):007:0> Dir["/**/*"]
=> ["/one/two"]
irb(main):008:0> Dir["/***/*"]
=> ["/one/two"]
irb(main):009:0> Dir["/***/*/**"]
=> ["/one/two/three"]
irb(main):010:0> Dir["/***/*/**/**"]
=> ["/one/two/three/four"]
irb(main):011:0>

I've added recursive globbing functionality to my fork at samg/fakefs
