Description Michael Rennie CLA 2014-06-23 12:49:01 EDT 
Consider the following snippet:

var bar = 10; //trailing comment

function foo() {
    bar = 11;
}

1. put the cursor in the 'function' keyword
2. use the menu item or command to insert the JSDoc 
3. nothing happens

The problem is that the trailing comment from the var decl and the leading comment for the func decl are set to be the same (in esprima) - so the logic assumes there is already a comment and does nothing.

The best solution here would be to copy how JDT works - it doesn't matter if there is a comment, just insert every time you activate the commend (rather than try to do something cleaver).
