This allows RDoc to better generate documentation for methods following the Ruby core documentation guide (which omits aliases in call-seq in most cases). This makes documentation for methods defined in C more similar to methods defined in Ruby. For methods defined in Ruby, the method description of the aliased method is already not used (you have to explicitly document the alias to use it). Internally, this adds AnyMethod#has_call_seq? and #skip_description?, and updates Darkfish to: * only show the method name if there is a call-seq for the method, but the call-seq omits the method * to omit the method description if the method is an alias or has aliases and has a call-seq that does not include the method See discussion in https://github.com/ruby/ruby/pull/7316 for details. https://github.com/ruby/rdoc/commit/e3688de49b
