So what I said in 05, but also didn't the commit messages of 05 and 06
get mixed up / bad fixup in a WIP version? I.e. the first commit says
"use symbolic ref", but it's mostly about introducing the use of this
tar/untar pattern.

Whereas this continues the tarring pattern, and doesn't start using it,
and (presumably) is the mis-squashed commit that should have added this
whole tar thing after the first commit does the isolated
s/echo/symbolic-ref/ fix.
