From 2a41dfb03b93c3e5b7d1deca537276aed063a044 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Wed, 11 Aug 2010 03:36:41 -0500 Subject: [PATCH] Introduce advise() to print hints Like error(), warn(), and die(), advise() prints a short message with a formulaic prefix to stderr. It is local to revert.c for now because I am not sure this is the right API (we may want to take an array of advice lines or a boolean argument for easy suppression of unwanted advice).
