Ah, right. I had a nagging feeling that we had discussed this, and
indeed, I already participated in the discussion last July[1]. I even
apparently argued in favor of the new behavior[2]. Yikes. There goes my
mind.

Running "git am -3" for each patch which needs it does indeed
successfully apply the series.

Thanks for a quick response, and sorry for the noise.

[2] In http://thread.gmane.org/gmane.comp.version-control.git/274574/focus=274635,
    though I think there I more meant that in:

       git am
       git am -3
       git am

    the third one would not use "-3" again. So I was mostly confused
    that in:

       git am
       git am -3

    we would not use "-3" for the subsequent patches applied by that
    second invocation. So maybe that is a bug. I dunno. I could see
    arguments either way.
