IIUC, Vim doesn't allow you to know of the existence of a file to which you
have neither read nor write permission
Just found how to do it:
if glob("~/.viminfo") != "" && ! filewritable(expand("~/.viminfo")) ...
Works nice. glob("~/.viminfo") returns non-empty string if file
exists, even if it is unreadable and unwritable.
