It is underdocumented, but it works AFAIK. You can search the internet
for experiences with it.

OTOH, some people emulate colocated branches with `bzr switch'. The idea
is that you have a checkout for hacking that you bind to wathever branch
you chose to work on. For example, lets suppose that you created your
working checkout with:

bzr co trunk my-playground   # you need to do this only once

from now on, when you need a small feature, you create a branch for it:

bzr branch --no-tree trunk fix-foo

this is a very fast and inexpensive operation on a shared repository, as
it doesn't even require to create the working tree.

Now, if you want to work on `fix-foo', from `my-playground' you do

bzr switch ../fix-foo

you do something and, eventually

bzr commit -m "done!"

this will update `fix-foo'. Later, you can proced to merge the changes
from `fix-foo' into `trunk' as usual (taking care of the ChangeLog
issue.)

If now you wish to work on a new micro-feature:

cd ..    # from `my-playground'
bzr branch --no-tree fix-bar
cd my-playground
bzr status  # Test that you don't have pending changes!
bzr switch ../fix-bar

Note that, within a shared repository, you can organize your branches as
you wish, so it is advisable to make a directory `delayed-changes' and
create your mini-feature branches there.
