Message #3 received at submit <at> debbugs.gnu.org (full text, mbox):
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').

We can probably remove the "PAGER=" variable binding from that fuction
as well.
