I said latter.  From ruby-dev:25048:

  ~ % cat t
  require 'optparse'
  parser = OptionParser.new
  parser.on('--line') {
    puts 'opt=--line'
  }
  parser.parse!

  ~ % ruby t -l
  opt=--line
  ~ % ruby t --l
  opt=--line
  ~ % ruby t -L
  opt=--line
  ~ % ruby t --L
  opt=--line


But, thanks for nobu, it seems that optparse.rb was modified after
[ruby-dev:25048] was posted.  We get following result now:

  % cat t
  require 'optparse'

  parser = OptionParser.new
  parser.on('--line') {
    puts 'opt=--line'
  }
  parser.parse!

  % ruby t -L
  /usr/lib/ruby/1.9/optparse.rb:1440:in `complete': invalid option: -L (OptionParser::InvalidOption)
	  from /usr/lib/ruby/1.9/optparse.rb:1438:in `catch'
	  from /usr/lib/ruby/1.9/optparse.rb:1438:in `complete'
	  from /usr/lib/ruby/1.9/optparse.rb:1297:in `order!'
