I am using:
Windows 10 x64
Git version 2.6.2.windows.1
Notepad2 x64 (this one overrides notepad)

.gitconfig

[core]
    editor = notepad
    autocrlf = true (also tried false)
  ...

When I do git config -e --global:

git config --global -e
unix2dos: C:/Users/user/.gitconfig MODE 0100644  (regular file)
unix2dos: using C:/Users/user/d2utmphK5NvM as temporary file
unix2dos: converting file C:/Users/user/.gitconfig to DOS format...
dos2unix: C:/Users/user/.gitconfig MODE 0100644  (regular file)
dos2unix: using C:/Users/user/d2utmpW2rV1K as temporary file
dos2unix: converting file C:/Users/user/.gitconfig to Unix format...

When i do git commit --amend (just to do a commit):

git commit --amend
unix2dos: path/public/.git/COMMIT_EDITMSG MODE 0100644  (regular file)
unix2dos: using path/public/.git/d2utmpX1LaLG as temporary file
unix2dos: converting file path/public/.git/COMMIT_EDITMSG to DOS format...

error: There was a problem with the editor 'notepad'.
Please supply the message using either -m or -F option.

Why do I get these messages? When I have atom as my editor it doesn't give me these messages...
