This has been reported on the Tramp mailing list, see
<https://lists.gnu.org/archive/html/tramp-devel/2021-10/msg00026.html>.

If you run Emacs on MS Windows, and you try to print the git log of a
remote file, you don't get anything. This is because vc-print-log has
emitted the following command:

--8<---------------cut here---------------start------------->8---
git --no-pager log --no-color -n 2000 -- \:\(literal\)c\:/tmp/tramp/README
--8<---------------cut here---------------end--------------->8---

See the leading drive letter "c:" in the file name. The problem is
`vc-git--literal-pathspec', which calls `expand-file-name' on the
*local* part of the remote file name.

A fix could be

--8<---------------cut here---------------start------------->8---
(defun vc-git--literal-pathspec (file)
  "Prepend :(literal) path magic to FILE."
  ;; Good example of file name that needs this: "test[56].xx".
  (when file
    ;; Expand abbreviated file names.
    (concat ":(literal)" (file-local-name (expand-file-name file)))))
--8<---------------cut here---------------end--------------->8---
