EDITOR ("C:\\Programmi (x86)\\Notepad++\\notepad++.exe")
## (i.e., double backslashes).
## or
EDITOR ("C:/Programmi (x86)/Notepad++/notepad++.exe")
## (forward slashes)

If it doesn't work, perhaps even quadruple backslashes.

On POSIX systems (incl. MinGW under Windows) "\" is an escape character. So
to have a " you'll have to escape it as well using "\\"
