[PATCH v3 8/9] user-manual: Flesh out uncommitted changes and submodule updates

From: "W. Trevor King" <redacted>

If you try and update a submodule with a dirty working directory, you
get an error message like:

  $ git submodule update
  error: Your local changes to the following files would be overwritten by checkout:
  ...
  Please, commit your changes or stash them before you can switch branches.
  Aborting
  ...

Mention this in the submodule notes.  The previous phrase was short
enough that I originally thought it might have been referring to the
reflog note (obviously, uncommitted changes will not show up in the
reflog either ;).

 NOTE: The changes are still visible in the submodule's reflog.
 
-This is not the case if you did not commit your changes.
+If you did not commit your submodule changes, the changes will *not*
+be silently overwritten.  Instead, you get the usual warning about not
+being able switch from a dirty branch.
