#1 Comments at end of file cause parse error

[Alex Bradley]

A single-line (//) comment as the last line of a .rub file appears to cause a parse error (see below).

This problem does not occur if an extra newline is added after the comment.

tyRuBa.parser.ParseException: Encountered "//" at line 34, column 1.
Was expecting one of:
<EOF>
"#include" ...
"#library" ...
"TYPE" ...
":-" ...
<IDENTIFIER> ...
