Receiving a log message from svnlook through a Windows package

I am trying to prepare a post-commit hook for my svn repository. So I need a log message from the last commit that I get with the command svnlook log -r %REV% %REPOS%. Filling a fragment with appropriate parameters I get the following multline log message:

This
is
my
transaction.

It works well. Now I put this in a .bat file:

@ECHO OFF

REM just for testing purpose...
SET REPOS=C:\repo
SET REV=40

FOR /F %%i in ('svnlook log -r %REV% %REPOS%') do SET VAR=%%i

ECHO %VAR%

When I execute the script, only the last line is output transaction.. For-loop is a snippet from which I thought it would read svnlook's output %var%.

My approach is to get the log message in a variable that I pass to another exe file as a parameter. But that will not work. I do not know how to use the loop correctly.

exe .

script (@ PA.)

@ECHO OFF
setlocal enabledelayedexpansion

SET REPOS=C:\repo
SET REV=40

SET MSG=
FOR /F %%i in ('svnlook log -r %REV% %REPOS%') do SET VAR=!VAR! %%i
ECHO !VAR!

This is my transaction. , .

rem ** The two empty lines are NECESSARY

SET REPOS=C:\Users\CH.ROSESOFT\Downloads\t3\repo

SET MSG=
FOR /F %%i in ('svnlook log -r %REV% %REPOS%') do (
    SET "VAR=!VAR!!LF!%%i"
    SET "PAR=!PAR!^^!LF!!LF!%%i"

ECHO !VAR!

without delimiters, some words will be missing

here is my pre-commit script that i just finished writing

if you set debug to 1, it will fail all the time and you will see messages with some var output

@echo off

set DEBUG=0
