Nit: Mike was wrong, this menu is in fact deletable; so just eliminate this
first comment line and capitalize "Ignore" on the next line.

Done.

Nit: I agree with Mike that this should be a DCHECK until you actually need to
handle other types.

[yefimt, 2012/07/31 00:10:11]

Done.

[Peter Kasting, 2012/07/26 20:37:17]

I reiterate: Why are these calls happening here instead of in BrowserActionView?
 Then that class wouldn't need to expose button(), dealing with ownership could
be simpler, etc.

Done.
