Thanks Ævar for doing this. I wanted to be there, but I took a much

     9.  Reftable has a set of files that go together. May want debugging tool
         to dump the content of a binary reftable file. But we can
         incrementally add those

The patch series includes a test-tool for dumping both individual
tables and a stack of tables. It's not super-polished, but it gets the
job done.

$ touch a ; ~/vc/git/git add a; ~/vc/git/git commit -mx

$  ~/vc/git/bin-wrappers/test-tool  dump-reftable -t
