sorry, didn't notice you inlined this in the header. Definition should be in a
cc file.

No problem; done.  PTAL: I wrapped it in a class whereas it wasn't before
because I was getting linker errors.  (Thanks for putting up with my Chromium
newness, haha; I appreciate the push for high code quality.)

+  views::Textfield* textfield = new views::Textfield();
+  textfield->set_placeholder_text(
+      l10n_util::GetStringUTF16(IDS_AUTOFILL_DIALOG_PLACEHOLDER_CVC));
+  textfield->set_default_width_in_chars(8);
+  textfield->SetTextInputType(ui::TextInputType::TEXT_INPUT_TYPE_NUMBER);
+  return textfield;
+}
