Hmm, is the "valid for add and update" part we want to keep?  I do
not think it is a crime if some other subcommand accepted --verbose
option but its output under verbose mode and normal mode happened to
be the same.

I doubt it would take a lot of imagination to see that people would
want to see "git submodule status --verbose" to get richer output,
and at that point, "progress of checkout" as part of the description
of the "--verbose" option does not make any sense.  Perhaps the
second part that is specific to "add" and "update" subcommands
should move to the description of these two subcommands?

I dunno.

Compare $depth and $verbose, and think what would happen if the end
user had an environment variable whose name happened to be $depth or
$verbose.  Does this script misbehave under such a stray $verbose?
What does the existing script do to prevent it from misbehaving when
a stray $depth exists in the environment?
