Solved it. I found this thread: [url]Question about {allfilepath|sep=,}]
So I changed your line from
"C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe" /command:commit /path:"{allfilepath|sep=*}" /closeonend:3
to
@set paths {allfilepath|sep=*}
"C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe" /command:commit /path:"{$paths}" /closeonend:3
And that worked!
Thanks, Ric.
