Question about cvs-all list

[Joshua Tinnin]

I was wondering if there's any way to tell where the commits on src are 
going. For instance, 5-STABLE is now getting changes which 5.4 isn't, 
at least AFAIK, and I know not everything in 6-CURRENT makes it to 
5-STABLE. I just saw a change come through for src/lib/libarchive, but 
I'm not sure if all branches get the change. Is there any way to tell 
from the commit message on the cvs-all list where the source changes 
are going? Or am I misunderstanding how the branches work?
