can make emacs hangs on kill-emacs

[bricewge]

direnv can cause emacs to hangs on exit, following are the minimal steps to reproduce it:

1. Opening a file as sudo through TRAMP and entering correct password
2. sudo --remove-timestamp
3. tramp-cleanup-all-connections, just afterward it already asks the sudo password (dismissing it)
4. Exiting emacs hangs for sudo password

I find this strange since you seems to verify that the file is not remote:

emacs-direnv/direnv.el

Line 129 in 468f2fb

(not (file-remote-p directory-name)))
