Oh boy. I could make some extra waves there if anyone considers this

This I can confirm, the auto-gc brought this down to 5.3G last night.
Aside, that process was also blatantly ignoring the gc.bigPackThreshold
settings, but that's another story.

Still, this is a lot worse than ealier: On April 7th the total size of
.git/objects/ was just 1571M here - a day later things started to go
downhill.

It's a bit saddening nothing has happened about this while everybody
should have been aware this will not resolve by itself - but rather get
worse over time :(

Data point about history rewriting, there are now 149k commits. If
rewriting a single commit takes just one second, the above number is
sensible.

Whatever improves the situation and assert it's not going to hit again.
