[BUGFIX] Fix comment parsing to support multiple comments (#672)

Because of an eager consumption of whitespace, the rule parsing would
swallow a trailing comment, meaning the comment for the next rule would
be affected. This patch addresses this by only consuming real whitespace
without comments after a rule.

Fixes #173
