object: git_object_short_id fails with core.abbrev string values by lrm29 · Pull Request #6944 · libgit2/libgit2
I think that probably this should be in the git_repository group, instead of git_object. (It's really about the repository's abbreviation settings.) This is a minor nit, and I've kept you waiting on a review for a long time, so I'm happy to make this change later today if you prefer. 🙏
Thanks for investigating and fixing.
