Normally, if you visit a file which Emacs is already visiting under
a different name, Emacs displays a message in the echo area and uses
the existing buffer visiting that file. This can happen on systems
that support symbolic links, or if you use a long file name on a
-system that truncates long file names. You can disable this feature
-by setting the variable @code{find-file-existing-other-name} to
-@code{nil}. Then if you visit the same file under two different names,
-you get a separate buffer for each file name.
