BUG: git log dies to SIGPIPE

What did you do before the bug happened? (Steps to reproduce your issue)
used `git log`, exiting the viewer (`less`) before reading the entire
commit history of the project
What did you expect to happen? (Expected behavior)
normal exit with status code 0
What happened instead? (Actual behavior)
git log dies to SIGPIPE after `less` exits
What's different between what you expected and what actually happened?
git does not exit normally as would be expected
Anything else you want to add:

FWIW, there was a discussion about this a few months ago:

Thanks, I'll check it out.

I may be a little unresponsive, I also saw this bug today, and there
is no such bug
in a small repository, it only appears in a large repository.

I now know that it comes from outside git, this is really bad.

Please see the discussion starting at
https://lore.kernel.org/git/YAG%2FvzctP4JwSp5x@zira.vinc17.org/ about
whether this is even considered a bug, but in any case the causes are
well understood.
