I read the docstring of `vc-pull', which is used by `package-vc-upgrade'.  It says:  --------------------------------------------------------------------------  "Update the current fileset or branch.  You must be visiting a version controlled file, or in a `vc-dir' buffer.  ..." --------------------------------------------------------------------------  But `vc-dir' is a user command other than a function, it will open a new buffer and return nil.  In consideration of the fact that `vc-pull' is an async function, it is not easy for us to  kill the `vc-diff' buffer right after the pull operation.  As you suggested earlier, maybe we need to modify vc.el, making the restriction looser?  Also, I noticed that the maintainer bind `default-directory' in this commit:  https://github.com/emacs-mirror/emacs/commit/7ab556b57631cb28db86b89ba296bc0599d9a399  Improve robustness of 'package-vc-update' Regards
