strip_heredoc() public

Strips indentation in heredocs.

For example in

if options[:usage]
  puts <<-USAGE.strip_heredoc
    This command does such and such.

    Supported options are:
      -h         This message

the user would see the usage message aligned against the left margin.

Technically, it looks for the least indented non-empty line in the whole string, and removes that amount of leading whitespace.
