Bug #2578

  Hi, 
 
  While revising the rubyspecs for Kernel#require, I noticed the following difference between 1.8 and 1.9. If $LOAD_PATH is empty, requiring a path relative to the CWD raises a LoadError on 1.8 but succeeds on 1.9. Adding any entry to $LOAD_PATH, even a nonexistent directory, causes the relative require to succeed. 
 
  I've tried searching for a ticket related to this but was unable to find one. Is this a bug in 1.8? If not a bug, could you please explain the reason for the difference. 
 
  $ cat a.rb 
  puts 1 
 
  $ cat b.rb  
  p $LOAD_PATH.clear 
  require './a.rb' 
 
  $ cat c.rb  
  p $LOAD_PATH.clear 
  p $LOAD_PATH << "irrelevant_dir" 
  require './a.rb' 
 
  $ ruby1.8.7 -v b.rb  
  ruby 1.8.7 (2009-12-24 patchlevel 248) [i686-darwin9.8.0] 
  [] 
  b.rb:2:in `require': no such file to load -- ./a.rb (LoadError) 
          from b.rb:2 
 
  $ ruby1.9 -v b.rb  
  ruby 1.9.2dev (2009-12-16 trunk 26107) [i386-darwin9.8.0]

  Thanks,
