$vfvp/packs-cp-full/opt/vim-tagbar/README.md
my fork of the excellent $GRs/d-CP/d-Vim-Vim/r-preservim-tagbar with thanks to the developers

git pull --unshallow
git remote -v # check remote locations
git remote add upstream https://github.com/preservim/tagbar
git fetch upstream # grab the changed upstream
git merge upstream/master -m '1 commit behind' # merges in the changes
rg HEAD # ripgrep for any conflicts
in vim: /^<<<<<<< HEAD$\|^=======$\|^>>>>>>> upstream/master$
ga . # if necessary
gic '1 commit behind'
git merge --abort # undo the merge
git push
