+ * Output from "git log --decorate" mentions HEAD when it points at a
+ tip of an branch differently from a detached HEAD.

+ * "git branch" on a detached HEAD always said "(detached from xyz)",
+ even when "git status" would report "detached at xyz". The HEAD is
+ actually at xyz and haven't been moved since it was detached in
+ such a case, but the user cannot read what the current value of
+ HEAD is when "detached from" is used.

+ "cd ''" which silently behaves as a no-op.
