That is an issue in rubocop.  It traverses the tree hierarchy using:

  Dir["somepath/**/*"]

Which is the equivalent of:

  Dir.glob( "somepath/**/*", 0 )

0 is the flag parameter which be made File::FNM_DOTMATCH to match
dotfiles (including '.' and '..'. So the Dir[] needs to be rewritten to
something like:

 Dir.glob("somepath/**/*", File::FNM_DOTMATCH)

And skip '.' and '..'.

Related code is target_files_in_dir method:

https://github.com/bbatsov/rubocop/blob/master/lib/rubocop/target_finder.rb#L58


The actual filtering via Include/Exclude, happens AFTER the tree
traversal (by invoking file_to_include?(file).  So whatever you put in
the config file, it is never going to find dotfiles.
