EditorHelper doesn't work on Windows because of the lack of tty.

There is however one small catch with this, if you're editor requires parameters like notepad++ with ' -multiInst -nosession' this will not work. Instead you have to create a cmd-file which contains the command and parameters like ``"C:\Program Files (x86)\Notepad++\notepad++.exe" -multiInst -nosession %1` and then change your editor-env value to point to the cmd-file.

Then it works.
