The is_binary_data method, used in repositories_controller.rb#124, is :

def is_binary_data?
  ( self.count( "^ -~", "^\r\n" ) / self.size > 0.3 || self.count( "\x00" ) > 0 ) unless empty?
end

Applied to the attached file :

str=''
File.open("test_color.sh", "r") { |f|
    str = f.read
}
(str.count("^ -~", "^\r\n") +0.0)/ str.length
=> 0.311345646437995

Which clearly is not < 0.3, so that file is downloaded instead of being displayed,
when one want to view it.
