Hi,

With emacs -Q, visit any file and say C-u vc-register.  
This yields an error: "Wrong type argument: symbolp, 4".

The interactive spec of vc-register seems to be a remnant of a previous
implementation that is no longer applicable, so I suggest simply
removing it:

diff --git a/lisp/vc/vc.el b/lisp/vc/vc.el
index 4cfd1790266..9f65ab187ce 100644

Yes, it looks like it should have been removed in commit 2f4f92007956.

Done it now, on the emacs-30 branch.  Thanks.
