[PATCH 1/1] add: use advise function to display hints

["Heba Waly via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Heba Waly <heba.waly@xxxxxxxxx>

Use the advise function in advice.c to display hints to the users, as
it provides a neat and a standard format for hint messages, i.e: the
text is colored in yellow and the line starts by the word "hint:".
