Version control "Register" operation

[cwcarlson]

In a previous version of Emacs, I'm not sure how long ago, when I did a 
"vc-register" operation, Emacs would automatically open a buffer for the 
"Description."  This would allow me to enter a description of the file 
being registered for RCS, CVS or SVN.

Now I find that "vc-register" just registers the file with no 
description.  I've looked in the vc*.el files and cannot see where it 
even considers opening a buffer for the description.

Is this a feature that has been removed?

Thanks,
Chris
