Actually, "bzr merge" does not create any commits on the branch -- you
need to run "bzr commit" afterwards (possibly after resolving
conflicts).  The control files for the working tree record a pending
merge, which gets recorded when you get round to the commit.

So you can easily check if there were any tree changes resulting from the merge.

If there aren't, or you made the merge by mistake, you can make a call
to "bzr revert" to clean things up without ever having created a new
revision.
