Of course, there is no difference between HEAD and HEAD. It's both the
same revision number :) I'm not sure, why you tried this. But it's not
HEAD in tags/... and HEAD in trunk/. HEAD is the latest revision number
of the whole repository (svn doesn't count separately for trunk,
branches and tags - every change increases the revision number)

Of course it's just replaced. What Merge does here is nothing lese than
getting the diff between revisions 87 and HEAD in tags/... and apply
this diff to trunk/.... And when I take a quick view over
svn diff -r87:HEAD tags/5.0.0-2/debian/changelog
it shows me, that entries from the changelog file were removed, that are
part of the changelog file in trunk. So these entries will removed, when
you apply the diff.

It can only apply changes between revisions to a file. Simply merging
the entries and check for entries, that can be find in both files, is
not a feature of svn merge (at least I don't know it). There you
probably need some other kind of tool.
