Re: Bug in grammar for paths

No it is correct. Sometimes it is possible to distinguish two coordinates
without the separator.  For example

1.0-42.0

In those situations, the comma and whitespace are not required.  Obviously,
if the second number was positive, you would need a comma and/or whitespace.
