This was copied from: activesupport/lib/active_support/core_ext/string/strip.rb
Instead of importing the whole activesupport library, we are only importing this one method.
Is this safe? The assumption is that the CLI will not be included in other projects as a gem. That mitigates possible side effects.
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 ... USAGE end
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.
