According to the book
svn.branchmerge.commonuses.wholebr), this is wrong, as it will not only
get the changes you've made to your branch, but will also remove any
changes that have been done on the trunk since the branch was created.
Which is (obviously) not what you want.

You need to get the revision the branch was created at (or, rather, the
last revision at which the branch was in sync with the trunk--either
when it was created, or the last time it was merged), and then do a
merge of the changes on the branch since then:

svn merge -r 14:HEAD ./branches/bugfix1/ ./trunk

(assuming that the branch was created/last merged at revision 14).

Incidentally, I found the examples in this section of the book (and the
later reference listing for svn merge) to be somewhat confusing, as they
assume that you're in a working copy of the trunk, without stating that
that's where you need to be. Perhaps these could be revisited and made
