This patch provides new informative help messages in the display of 'git status' (at the top) during conflicts, rebase, am, bisect or cherry-pick process. The new messages are not shown when using options such as -s or --porcelain. The messages about the current situation of the user are always displayed but the advices on what the user needs to do in order to resume a rebase/bisect/am/commit after resolving conflicts can be hidden by setting advice.statushints to 'false' in the config file. Thus, information about the updated advice.statushints key are added in Documentation/config.txt. Also, the test t7060-wt-status.sh is now working with the new help messages. Tests about suggestions of "git rm" are also added.
