But I don't know how far we would go protecting other worktrees. You give --force and that usually means "Yes I know what I'm doing, don't stop me". If --force rejects in this case, what would be the real force, --force --force maybe, or fall back to "git update-ref"? > > #and the other worktree is now corrupted: > > > /c/tmp/wt (master) > $ git status > On branch master > Changes to be committed: > (use "git reset HEAD <file>..." to unstage) > > modified: txt.txt > deleted: txtb.txt > > > > greetings f.kulow -- Duy
