vc-arch-mode-line-string has the following implementation:
(defun vc-arch-mode-line-string (file)
"Return string for placement in modeline by `vc-mode-line' for FILE."
(let ((rev (vc-working-revision file)))
(dolist (rule vc-arch-mode-line-rewrite)
(if (string-match (car rule) rev)
(setq rev (replace-match (cdr rule) t nil rev))))
(format "Arch%c%s"
(case (vc-state file)
((up-to-date needs-update) ?-)
(added ?@)
(t ?:))
rev)))
Obviously, rev is nil. It is computed via (vc-working-revision file),
which shall call (vc-arch-working-revision file) internally. No idea,
why it returns nil.
It could still be Tramp, but maybe you ask the vc-arch wizards first.
Best regards, Michael.
