Blocks with comments only throw ParseError

[StanAngeloff]

Run the following on coffeescript.org:

a: 1
if a
    # I don't like comments
else
    a: 2

It used to compile just fine, but on master it seems comments cannot be the only token in a block. May have something to do with how the rewriter is adjusting them? If you put a newline just before the comment, it will compile OK.

I was going to write a long explanation about how this doesn't work because comments don't affect indentation. But instead, I added a rule for TERMINATOR Commentwhich makes it so that an empty comment can be used as a valid Block in the grammar. Here's the passing test:

result: if false
  # comment
else
  27

ok result is 27

Closing the ticket.

We don't say this often enough: Thank you.

This is fixed via #4572. Sorry it took awhile.
