#strip_heredocObject

Strips indentation in heredocs.

For example in

if options[:usage]
  puts "This command does such and such.\n\nSupported options are:\n-h         This message\n...\n".strip_heredoc
end

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

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