I ran git fetch --prune and I see:
- [deleted] (none) -> origin/branch_name_here
I can not tell from the branch name if it was an important reference.
How do I find out where origin/branch_name_here was pointing?
It has not been used in a long time and so it is not listed in git reflog, and either way I do not know the commit message associated with origin/branch_name_here.
I have run git config --local gc.auto 0 to disable garbage collection in order to prevent losing the commits.
git fsck --full --no-reflogs | cut -d' ' -f3 | xargs -P2 git log --oneline | grep 'branch_name_here'
shows nothing because branch_name_here is not part of the commit message.
looking through .git/objects/?? and sorting by file modification/creation date would take forever.
I suspect the answer is the same with respect to pruned tags... no.
