Isn't this rather an error in vc-git.el, et al? The relevant function
there is
(defun vc-git--call (buffer command &rest args)
;; We don't need to care the arguments. If there is a file name, it
;; is always a relative one. This works also for remote
;; directories. We enable `inhibit-null-byte-detection', otherwise
;; Tramp's eol conversion might be confused.
(let ((inhibit-null-byte-detection t)
(coding-system-for-read vc-git-commits-coding-system)
(coding-system-for-write vc-git-commits-coding-system)
(process-environment (cons "PAGER=" process-environment)))
(apply 'process-file vc-git-program nil buffer nil command args)))
As you see, PAGER is set (and overwrites Tramp settings). Such changed
process-environment is taken into account since Tramp 2.2.11.
Best regards, Michael.
