`files-equal-p' still returns t for two non-existing files. Shall be
fixed too.

Btw, this is the only primitive function which has the prefix "files-",
all other start with prefix "file-". Is this necessary?

(No it is not important, but if we want change it, we must do it before
the 24.1 release).

Best regards, Michael.
