"To contain developer changes?" How is that different than what I'm
talking about? You can easily give every developer a private branch in
Subversion -- just copy the trunk directory to a new branch directory,
make the developer work on the branch, then merge the branch back to the
trunk. A lot of teams do this, it's a common use pattern.

No, it's a *changeset* which causes or fixes a bug. Not a single file
revision or line of code. I mean, sure, yes, a line of code can cause a
bug -- but you need to stop thinking down at that level. It's not the
"subversion way" to think about per-file revisions!

When hunting a bug, you can just as easily do a 'binary search' on
global revison numbers (changeset numbers), just as you do on revisions
within a single RCS file.

Once you've determined that revision N caused or fixed the bug, you see
which branch that changeset was committed to, then look at logs (or
policies) and figure out where else that changeset was ported (and/or
still needs to be ported to.)
