Bug #8006: Dir.glob behaves differently on 1.9.3 and 2.0

While testing an application of mine with Ruby 2.0 I came across the 
following problem with Dir.glob where the pattern `FOO/BAR/**/*` does 
not match the directory `FOO/BAR` anymore because the implicit 
directories '.' and '..' don't get matched anymore.

Used files:

 $ find data/webgen/basic_website_template/
 data/webgen/basic_website_template/
 data/webgen/basic_website_template/ext
 data/webgen/basic_website_template/ext/init.rb
 data/webgen/basic_website_template/webgen.config
 data/webgen/basic_website_template/src
 data/webgen/basic_website_template/src/.gitignore

With Ruby 1.9.3-p327:

  1.9.3-p327 :001 > Dir.glob('data/webgen/basic_website_template/**/*', 
File::FNM_PATHNAME|File::FNM_DOTMATCH|File::FNM_CASEFOLD)
   => ["data/webgen/basic_website_template/.", 
"data/webgen/basic_website_template/ext", 
"data/webgen/basic_website_template/ext/.", 
"data/webgen/basic_website_template/ext/..",

With Ruby 2.0.0-p0:

After some more experimenting, it seems that the '**' operator doesn't 
act the same like in 1.9.3:

For your information, I have fixed this problem in my code, see the 
((<commit on 
Github|URL:https://github.com/gettalong/webgen/commit/8c49da9...)).

Would be good, though, to know whether this is intentional or not.

Thanks!
