I would like to do
svn commit -m \"\"

Commit by: firstuser
Bug track: 92
I had the same problem and while Claes Mogren's answer does not work with cmd.exe it made me think if there's a shell on Windows that could do that.

Using PowerShell shell you can achieve this using following command:
svn ci -m "reference to Ninject fixed`nsome ignores added"
Notice the combination of backqoute and n in the message
`n
