bug#64589: 30.0.50; smie-config-guess can break ruby indentation

[Aaron Jensen]

In repro.rb:

def some_method
  return some_other_method(
    some_argument
  )
end

emacs -Q repro.rb
M-x smie-config-guess

Type:

foo(
x
)

The x will not be indented. If smie-config-guess is omitted, it indents
as expected.
