I have a problem with my pre-revprop-change. I want to allow changes to the log message, but only for the author himself OR a set admin. The code I've edited is this one: https://stackoverflow.com/a/18005347/16739479

I've edited this part, but it doesn't work as it should:

set admin = muellerp
set AUTHOR=
for /f "delims=" %%a in ('svnlook author -r %REV% %REPOS%') do @set AUTHOR=%%a
if /I not '%AUTHOR%'=='%user%' if /I not '%user%'=='
