is a user "new" if this is their *first* (and only first?) time running the
dialog?

[Ilya Sherman, 2013/03/09 01:58:57]

No, it's as the comment says.  Do you have a different name that you'd prefer
for this enum constant?

+    // User signed in, no Wallet items, no verified Autofill profiles.
+    DIALOG_NEW_USER_SIGNED_IN,
+    // User signed in, no Wallet items, but 1+ verified Autofill profiles.

nit: if you could change "1+" to something that doesn't look like maths (i.e.
"User signed in, no Wallet items, has a verified Autofill profile." it'd be
easier for sleepy Dans to parse, IMO.

Done.
