The commit log message should describe what kind of consistency you are
talking about to people who are not familiar with the topic.

Output format from "git add -n $path" lists path to blobs that are going
to be added on a single line, separated with SP.  On the other hand, the
suggested "git add -u -n" shows one path per line, like "add '<file>'\n".
Of course, these two are inconsistent.

Plain "git add -n" can afford to only say names of paths, as all it does
is to add (update).  However, "git add -u" needs to be able to express
"remove" somehow.  So if we need to have them formatted the same way, we
need to unify with the "git add -n -u" format.  Incidentally, this is
consistent with how 'update-index' says it.

I do not think we need to worry about people who wrote script around
output from "git add -n".  Output from Porcelain commands is a fair game
for improvements.
