That's not what the book says. The book says that in order to merge a
branch into the trunk, the user should be careful about which two URLs
are compared. The two URLs should *not* be {branch@HEAD, trunk@HEAD}.
That would result in the quoted affect above.

Instead, you should be comparing the URLs {branch@BIRTH, branch@HEAD},
where BIRTH is the revision in which the branch was first created. By
comparing those two URLs, you're creating a composite "patch" which
exactly describes all the changes that happened on the branch.
