Tweak error message to avoid misleading the user

Users who turn ignore-without-code on are likely at first to
encounter cases where their existing ignores are too broad.
The previous hint spelling was useful, however could encourage
users to just ignore everything which was already ignored rather
than actually reviewing the code. This change removes the implication
that the correct course is to blindly update the ignore comment
while still containing the useful information about what is ignored.
