"git apply" specifically calls out when it is falling back to 3way merge application. Since the order changed to preferring 3way and falling back to direct application, continue that behavior by printing whenever 3way fails and git has to fall back.
That makes sense.
Add a --quiet flag to "git apply" so the user can turn down the verbosity.
It makes sense, too. But aren't they a different change that should belong to a separate patch? After all, the first point is to give the same kind of fallback warning/report as we used to before we swapped the fallback order, and no users needed extra "more silent" setting to deal with the fallback warning messages. Allowing to set the verbosity even lower may be desirable, but that is an independent new feature, isn't it? I wonder if it is the more correct approach to replace OPT__VERBOSE() with OPT_VERBOSITY() here, instead of adding a separate OPT_SET_INT() like you did. Thanks.
