Thank you, done, in 114732. Please review when you have the time.

Some further questions:

1) Is `assoc' any different from `left' in practice?

2) `ruby-smie-grammar' has a FIXME at the top. What kind of Cucumber 
support do you suppose is missing? The "Given /toto/ do" example in 
ruby.rb looks fine, mostly due to the syntax-propertize-function, which 
hasn't changed.

3) Please take a look at the following example:

foo_bar_tee(1, 2, 3)
  .qux

What would be the best way to make it work (and also similar example 
with the dot on the first line)?

Add another two cases to `ruby-smie-rules', for the token "."? That 
wouldn't exactly, I think, work because `ruby-smie--forward-token' and 
its counterpart like to concatenate the dot with the identifier that 
goes after it.
