bug#16811: 24.3.50; [ruby-mode] Implicit hash indentation bug

[Bozhidar Batsov]

This nested hash literal is indented correctly:

{
  'HashSyntax' => {
    'EnforcedStyle'   => 'ruby19',
    'SupportedStyles' => %w(ruby19 hash_rockets)
  },
  'SpaceAroundOperators' => { 'Enabled' => true }
}

This one, however, is not:

method('HashSyntax' => {
                        'EnforcedStyle'   => 'ruby19',
                        'SupportedStyles' => %w(ruby19 hash_rockets)
                      },
       'SpaceAroundOperators' => { 'Enabled' => true })

Should be:

method('HashSyntax' => {
         'EnforcedStyle'   => 'ruby19',
         'SupportedStyles' => %w(ruby19 hash_rockets)
       },
       'SpaceAroundOperators' => { 'Enabled' => true })


The fact that the hash is implicit (lacking {}) seems to mess with the
indentation logic.
