docparser issues with dojo.declare

[robert.coup@…]

dojo.declare causes two issues with the docparser:

• declarations with no ancestor (dojo.declare("my.new.class", null, { ... });) are not picked up.
• in the body, methods declared myMethod : function(a,b,c) { ... } are not picked up due to odd whitespace-matching around the ":"
