git-update-index -q

Karl Chen· Sep 2, 2008, 17:51 UTC · lore

The git-update-index man page entry for -q says:

       -q
           Quiet. If --refresh finds that the index needs an
           update, the default behavior is to error out. This
           option makes git-update-index continue anyway.

Can someone explain this to me? As far as I can tell, git-update-index without -q does not error out after the first update.
