TemplateSyntaxError: expected token 'name', got ')'

[vpelletier]

I get this error when writign a macro with a trailing comma:

{% macro foo (
bar,
)%}
...
{% endmacro %}

Although it's not strictly required to make the macro work (I can just drop the trailing comma), it's quite convenient VCS-wise: if I add another parameter, I don't get a diff on the last existing parameter just because I need to add a comma.
