Create a CVS repository in the present working directory:
$ cvs -d "$PWD/cvsroot" init

Create multiple working directories:
$ cvs -d "$PWD/cvsroot" checkout -d dir1 .
$ cvs -d "$PWD/cvsroot" checkout -d dir2 .

Create a file in one of the working directories:
$ touch dir1/file

Check in the file:
C-x v d dir1 RET
SPC m C-x v v C-x v v C-c C-c q

Mark the file in the other working directory:
C-x v d dir2 RET
SPC m

vc-next-action prints an error message:
C-x v v yes RET

Cannot open load file: No such file or directory, vc-nil

The patch below seems to fix this particular scenario.

I'm not sure we want to expend much effort on supporting CVS this day 
and age, but if the one-liner change is enough, all the better.

You'd have to upgrade to a newer Emacs, though. 26.3 is quite old.

Thanks.  If this solves the problem, it's okay to install it on the
emacs-29 branch.

Thank you, done. At least, it fixes things in my testing.

I'm going to close this report now, but Beth, please feel free to get 
back to us regarding the fix if you find it not working for some reason.
