This is great, spotted / questions so far:
* git graph --blah says you need to enable the config, should say
"unknown option --blah <help>". I.e. overzelous config guard.
* On a big repo (git show-ref -s | ~/g/git/git-graph --write
--update-head) is as of writing this still hanging for me, but strace
shows it's brk()-ing. Presumably just still busy, a progress bar would
be very nice.
* Shouldn't there be a pack.useGraph option so this gets auto-updated on
repack? I understand this series is a WIP, so that's more a "is that
the UI" than "it needs now".
