  New Revision: 66976

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=66976

  Log:
    _leaf_helpers.erb: some functions are not leaf
    
    If a function has rb_warning() that is not a leaf because warning
    ultimately is a method call of Warning#warn.
    
    If a function has rb_name_error() that is not a leaf because
    NameError is allocated, then initialized.  This of course
    involves calling NameError#initialize.
