What steps will reproduce the problem? 1. Use IN as a field name in a literal object. E.g.

var foo = { X : 10, IN : 20, OUT : 30, Y : 40 };

2. Indent lines with <TAB> (with bounce-mode indentation turned off)

3. Note that the IN line gets indented extra.

What is the expected output? What do you see instead?

I see this:

var foo = { X : 10, IN : 20, OUT : 30, Y : 40 };

I expect this:

var foo = { X : 10, IN : 20, OUT : 30, Y : 40 };

What version of the product are you using? On what operating system?

js2-20080616a.el on GNU Emacs 22.0.99.1 (powerpc-apple-darwin8.9.0, Carbon Version 1.6.0) of 2007-05-06 on beagle

Please provide any additional information below.

I'm guessing that may have something to do with 'in' being a keyword. But unless I'm confused Javascript is case sensitive so 'IN' should not be treated specially. On the other hand, a quick look through the source didn't show up any obvious places where case is ignored or smashed so that guess may be totally wrong. And if I change the IN to say FOR or WHILE it still indents correctly, so it's not all upcased keywords that are a prooblem.

Here's a patch that seems to fix the problem:
