Configliere::Commandline#dashed_flag_for method is a little wonky

[kornypoet]

If a Settings object is defined with a underscored param, there is no way to recycle this param as a command line option.

#!/usr/bin/env ruby

require 'configliere' ; Settings.use(:commandline)

Settings.define :some_param, default: 'some val'
Settings.resolve!

p Settings.dashed_flag_for :some_param
#=> "--some-param=some val"

Which is only marginally useful because the string it returns does not match my original param definition. What would be great is a method that does this, but without altering the definition, so params can be recycled into another Configliere configured program. Is there some specific use-case for dashed_flag_for?
