Ahh, that's new. I guess I need to update my ancient b4-0.8.0 install..

But yes, with that, and the manual parent lookup (because otherwise
"--no-parent" will fetch *just* the patch itself, not even walking up
the single parent chain). it works.

Maybe a "--single-parent" or "--deadbeat-parent" option would be a good idea?

Anyway, with a more recent b4 version, the command

   b4 am --no-parent
CAHk-=wh6MxaCA4pXpt1F5Bn2__6MxCq0Dr-rES4i=MOL9ibjpg@mail.gmail.com

gets that series and only that series.
