Inconsistent reporting of missing @this in JsDoc

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run the linter on https://gist.github.com/2629373

What is the expected output?
No errors reported, because all of these methods are part of a prototype 
object, so it should be clear what 'this' will refer to.

What do you see instead?
The error MISSING_JSDOC_TAG_THIS is reported for the first two 'someMethod's 
but not for the third one.

What version of the product are you using?
2.3.5

I looked at the code a little bit, and I don't totally understand why this is 
happening, but I noticed that there appears to be an unused local variable, 
is_immediately_called:

There were a couple of errors in the original gist. Here's the fixed version: 
https://gist.github.com/2629373/d98435d0f022d1e6fc14d5fd714f80afb819c3d3

We only get the error in the first case. Essentially, wrapping everything in a 
function seems to suppress the error, and I'm not sure why.
