Here's a test that fails:
$ mkdir testrequire

$ echo '                   
module Kernel
  alias :require_basic :require
  def require(file_or_directory)
    if FileTest.directory?(file_or_directory)
      require "#{file_or_directory}/#{file_or_directory}"
    else
      fp = File.dirname(File.expand_path(file_or_directory))
      $: << fp
      r = require_basic file_or_directory
      i = $LOAD_PATH.index(fp)
      $LOAD_PATH.delete_at(i) if i
      return r
    end
  end
end

require "file2.rb"
' >testrequire/file1.rb 

$ echo "puts 'in file2.rb'" >testrequire/file2.rb

$ ruby testrequire/file1.rb 
testrequire/file1.rb:10:in `require': No such file to load -- file2.rb 
(LoadError)
        from testrequire/file1.rb:10:in `require'
        from testrequire/file1.rb:18

$ (cd testrequire && ruby file1.rb)
in file2.rb
