Indeed.

Some of the tests do delete reflogs (manually), and the refs backend
code has a test driver that performs that operation (along with some
others).  I could move git reflog remove out of that driver and into git
reflog, but I'm reluctant to do it just for the tests.  If there's a
non-test reason for it, I'll be happy to.

I've pushed a new version of this series to
https://github.com/dturner-tw/git/ on the pluggable-refs-preamble
branch.  The new version addresses Michael's comments from this around,
and makes a variable static as you suggested (and said you would squash
in).

Junio, now that Michael has marked this as reviewed, do you want to pull
from github, or do you want me to send a re-roll to the mailing list?

Thanks.
