reflog: implement subcommand to drop reflogs
While 'git-reflog(1)' currently allows users to expire reflogs and delete individual entries, it lacks functionality to completely remove reflogs for specific references. This becomes problematic in repositories where reflogs are not needed but continue to accumulate entries despite setting 'core.logAllRefUpdates=false'. Add a new 'drop' subcommand to git-reflog that allows users to delete the entire reflog for a specified reference. Include an '--all' flag to enable dropping all reflogs from all worktrees and an addon flag '--single-worktree', to only drop all reflogs from the current worktree. While here, remove an extraneous newline in the file. Signed-off-by: Karthik Nayak <karthik.188@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
