Where, if anywhere, are the new prefs declared (registered?)?

Without a registration call, can you still read old prefs?

[Miranda Callahan, 2010/12/14 01:03:49]

I added the new user pref registration to RegisterUserPrefs in predictor_api.cc.
 Very good point that I won't be able to read the old prefs!  :-)  I like your
answer in the previous comment that we could discard and delete the data in
local_state. Not only will it be quickly rebuilt, but it'll save a migration
check on startup.
