this class should probably be TabStripContextMenuController now that there is no
TabMenu:: namespace. (And you could drop Context to reduce the length.)

Done.

when would this be null?

[dpapad, 2011/05/11 23:30:20]

Again, I did not change these checks. tab_ is set to null in Cancel(). I am
guessing that it cant harm to have this check and avoid dereferencing a null
pointer in some corner case.

[Evan Stade, 2011/05/12 00:05:27]

so I guess it depends on whether you could call Cancel() and still get an
ExecuteCommand(). If this is possible, there should at least be a comment to
that effect which explains the conditions under which it might happen,
otherwise, this check shouldn't be here or should be a DCHECK.

[dpapad, 2011/05/12 00:34:25]

I will try and see and also ask James, since svn blame returns his name.
