Are the rest of these overrides (in which case we should add OVERRIDE) or not
(in which case we should add a comment to separate them).

[Greg Spencer (Chromium), 2011/08/11 22:19:32]

Done.

Maybe add ParseValue() here, even if it just calls the base class parser, to
make that explicit?

[Greg Spencer (Chromium), 2011/08/11 22:19:32]

Well, but that adds an additional virtual function call that isn't needed. 
Maybe I can just add a comment to that effect?

[stevenjb, 2011/08/12 21:32:37]

Fair enough. I don't think the overhead really matters, but it's obvious enough
without the empty function.

Do want the following to be virtual, i.e. would it ever make sense to
intentionally override them? Same for the new virtual methods in Cellular and
Virtual.

[Greg Spencer (Chromium), 2011/08/11 22:19:32]

You're right.  And they're just helper functions anyhow. Done.
