How to Get Rid off the Sticky Tag inside Emacs?

[Xin]

Hello,

When coding inside Emacs, one can use C-x v r to retrieve Tags, but
then the code will have a "Sticky Tag" with it. How can I get rid off
it?  I knew in terminal one can use cvs update -A, but not sure how to
do that inside Emacs. I though this should be a frequent usage ...

Thanks!

Xin
