You have baseline A. (the original release.)
You have baseline B. (the maintenance patch.)
You need the delta/diff of B - A.

You can do an 'svn log -v -r A+1:B svn_url' and parse the list of
changed files to build your hotfix patch.
 (A+1 is revision number of baseline A plus 1. B is the revision number
of baseline B.)

Or you can export both baselines and diff them to generate the the list
of changed files.

I would not use 'svn diff' to find the delta because, last I checked,
'svn diff' underreports differences because it doesn't walk into
directories in certain cases (dir_conflicts/evil_twins I think.)

Ignore my comment about merging. However, it may be possible to
*un*merge baseline A from baseline B, leaving just the hotfix tree.

How do you plan on handling files that were deleted in the hotfix...?
Overwriting only works for adding or modifying files.

AFAIK, there's no way to tell subversion to extract just the files
committed in revision 123 (i.e. the files in the changeset.)
