nit: and this can be in a separate CL, but the naming of this param, as well as
the description, is not super obvious to me.

I assume that it's to report something like: 20 history items deleted, 3
downloads deleted?

No, it is whether the settings that are being reset will be reported to Google
before being reset.

Updated comment. I was not super descriptive initially because this parameter is
already documented at
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/ui/....
