Feature #14463: Allow comments to precede dots in member expressions

----------------------------------------
I, coming from other languages, find it *extremely* odd that the first three are considered valid, but the fourth is a syntax error (tested in Ruby 2.3.4 + 2.5.0, Rubocop's parser for 2.3):

~~~ ruby
# 1
foo = -> {}
foo.
  call

# 2
foo = -> {}
foo.
  # comment
  call

# 3
foo = -> {}
foo
  .call

# 4
foo = -> {}
foo
  # comment
  .call
~~~

Any chance 4 could be fixed? (It looks more like a parser/spec bug than anything.)
