Just a question (feel free to ignore):

Will we get profiles other than this.profile_?
i.e. will this profile be the same as profile_?

or will it sometimes be profile_->GetOffTheRecordProfile()
or something else?

[Finnur, 2016/09/01 11:10:15]

No, it is an excellent question.
Yes, we can get a pointer to any random profile that is created/destroyed,
incognito or not. And we don't want to handle all of them. Addressed.

Optional: I'm found this hard to parse and I'm 
wondering if a different layout would help. WDYT 
of:

Profile* profile = incognito 
    ? (profile_->HasOffTheRecordProfile()
        ? profile_->GetOffTheRecordProfile() 
        : nullptr) 
    : profile_;

or

Profile* profile = 
    incognito ? 
        (profile_->HasOffTheRecordProfile() ?
            profile_->GetOffTheRecordProfile() :
            nullptr) :
        profile_;

If you decide to change the layout of the
ternary above, this could be formatted in 
a similar way.
