The only benefit from this move (apart from cleaner code) is that advice.amWorkDir should now show up in `git help --config`. There should be no regression since advice config is always read by the git_default_config(). While at there, use advise() like other code. We now get "hint: " prefix and the output is stderr instead of stdout (which is also the reason for the test update because stderr is checked in a following test and the extra advice can fail it).
