Thank you for your advice.
Base on the advice, I have rewritten the patch.

I explained the patch in the old mail:
    I wrote a patch to check out a branch under the point in cvs-tree
    buffer by hitting `>' to track the current emacs development:-P I
    found this function is useful. However patch is not clean enough. So
    I'd like to get your advice.

With the new patch, you can do the same on cvs-status buffer.

BTW, With gnuarch, finally I get what I wanted during writing 
the draft version of cvs-tree.el. I think you have interest:
