    -    Use the newer advise_if_enabled() machinery to show the advice.
    +    Since b3b18d1621 (advice: revamp advise API, 2020-03-02), we can use
    +    advise_if_enabled() to display an advice.  This API encapsulates three
    +    actions:
    +            1.- checking the visibility of the advice
    +
    +            2.- displaying the advice when appropriate
    +
    +            3.- displaying instructions on how to disable the advice, when
    +                appropriate
    +
    +    The code we have in builtin/add.c to display the ADVICE_ADD_IGNORED_FILE
    +    advice, is doing these three things.  However, the instructions
    +    displayed on how to disable the hint are not shown in the normalized way
    +    that advise_if_enabled() introduced.  This may cause distraction.
    +
    +    There is no reason not to use the new API here.  On the contrary, by
    +    using it we gain simplicity in the code and avoid possible distractions.
    +
    +    For these reasons, use the newer advise_if_enabled() machinery to show
    +    the ADVICE_ADD_IGNORED_FILE advice, and don't bother checking the
    +    visibility or displaying the instruction on how to disable the advice.

    -    Use the newer advise_if_enabled() machinery to show the advice.
    +    Since 93b0d86aaf (git-add: error out when given no arguments.,
    +    2006-12-20) we display a message when no arguments are given to "git
    +    add".
     
    -    We don't have a test for this.  Add one.
    +    Part of that message was converted to advice in bf66db37f1 (add: use
    +    advise function to display hints, 2020-01-07).
    +
    +    Following the same line of reasoning as in the previous commit, it is
    +    sensible to use advise_if_enabled() here.
    +
    +    Therefore, use advise_if_enabled() in builtin/add.c to show the
    +    ADVICE_ADD_EMPTY_PATHSPEC advice, and don't bother checking there the
    +    visibility of the advice or displaying the instruction on how to disable
    +    it.
    +
    +    Also add a test for these messages, in order to detect a possible
    +    change in them.

    -    Use the newer advise_if_enabled() machinery to show the advice.
    +    By following a similar reasoning as in previous commits, there are no
    +    reason why we should not use the advise_if_enabled() API to display the
    +    ADVICE_ADD_EMBEDDED_REPO advice.
     
    -    We don't have a test for this.  Add one.
    +    This advice was introduced in 532139940c (add: warn when adding an
    +    embedded repository, 2017-06-14).  Some tests were included in the
    +    commit, but none is testing this advice.  Which, note, we only want to
    +    display once per run.
     
    +    So, use the advise_if_enabled() machinery to show the
    +    ADVICE_ADD_EMBEDDED_REPO advice and include a test to notice any
    +    possible breakage.
