fn :strip_heredoc
doc(<<~DOC)
Strips indentation in heredocs.
For example:
puts strip_heredoc(<<-USAGE)
This command does such and such.
Supported options are:
-h This message
...
USAGE
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.

def call(string)
string.gsub(/^#{string.scan(/^[ \t]*(?=\S)/).min}/, "").tap do |stripped|
stripped.freeze if frozen?
end
