   - For Win32, $HOME is set by Vim if needed, see |$HOME-windows|.
   - When a "_gvimrc" file is not found, ".gvimrc" is tried too.  And vice
     versa.
+  - On Unix, if "~/.config/vim/gvimrc" or "$XDG_CONFIG_HOME/vim/gvimrc"

   The name of the first file found is stored in $MYGVIMRC, unless it was
   already set.
 - If the 'exrc' option is set (which is NOT the default) the file ./.gvimrc
