I'm still of two minds a little bit: conceptually, the current approach 
is a little cleaner because it forces the opt-in approach, and thus 
won't affect any command (or use of functions like 
vc-git--run-command-string outside of vc-git.el) that didn't opt into 
using literal pathspecs.

But my original approach is simpler and shorter, and together with an 
opt-out var seems to solve every problem so far. It doesn't need version 
detection either (a patch to have it work on remote hosts was discussed 
previously here).

So here's the patch (my current preferred solution for both emacs-28 and 
master).

Waiting for feedback from AndyM.
