Subject: 27.0.50; vc-dir + tramp hangs when there are stashes
Date: Fri, 20 Dec 2019 15:53:53 +0100

When visiting a remote git repo using tramp, if you subsequently run
'vc-dir', then emacs will hang forever if the remote repo has
stashes. This turned out to be to me having

         pager = less -FRXI

in my remote .gitconfig. Unsetting that fixes it, but vc-git should
perhaps take care to run git with '--no-pager' (it already does
something similar in 'vc-git-command').
