The same query with 's/| head -n 1/>/dev/null' is more expensive.  In fact
it is much more expensive than the non-incremental one (v2), and about
three times more expensive than non-limiting --full-history for explaining
the history of kernel/printk.c.

Hmm? Why is that, exactly? Does it walk over the same commit over and over 
and over again or something?

Can you combine --simplify-merges and --topo-order to get a fast version 
again (since --topo-order will force a non-incrmental walk)?

Heh, nice try to make my head explode ;-)  Not today, no, really, no...
