Comments enclosed in curly-braces not parsing in some cases

[tsandall]

This fails to parse:

package example

p {
  x = 1 # inline comment
  x = y
}

Error:

1 error occurred: /Users/torin/rego/comments1.rego:4: no match found, unexpected '{'

This is OK:

package example

p {
	x = y
    x = 1 # inline comment
}

Also, ast.ParseBody calls that supply non-enclosed/whitespace separated expressions are not parsing.
