Ah ha ha. Of course! I'm spending most of my time in Windows using
compiled unix tools - all my command-line intelligence has atrophied in
the face of batch files. :)

Much better - thanks again.

Aside from a changleog, there's no particularly good way to handle
deletions using this method. The gain in simplicity of distribution
unfortunately loses functionality. The ultimate solution would be to use
svn itself as a distribution method but that's not an option.
Thanks again for your help - it was driving me crazy.
If anyone else wants a windows batch file to do this, the following
worked for me (with great help from sed, sort and uniq):
@ECHO OFF
SETLOCAL DISABLEDELAYEDEXPANSION
REM Location of sed, sort and uniq
SET TOOLS=d:\utils\unix\usr\local\wbin
REM SVN root
SET SVN=svn://localhost/myproject/trunk/public
REM Patch path
SET PATCH=.\temp
REM Working copy root
SET WC=d:\projects\web\myproject\public
REM Convert backslashes to double backslahes for quoted sed expression
SET WCQ=%WC:\=\\%
echo Creating changed files list
REM Remove lines without an filename extension (assumed to be directories)
REM Extract the root path from the filename
svn diff -r PREV:HEAD --summarize %WC% | %TOOLS%\sed -e "/[.]/!d" |
%TOOLS%\sed -e "s/^[AM].* %WCQ%//pi" | %TOOLS%\sort | %TOOLS%\uniq >

SET URL=!FILE:\=/!
REM Export the file from the repository to the patch directory
svn export %SVN%/%URL% %PATCH%\%%A
)
ENDLOCAL
echo Cleaning up...
del files.txt
del directories.txt
:end
echo Done.
