If you visit two names for the same file, normally Emacs makes
two different buffers, but it warns you about the situation.
-@vindex find-file-existing-other-name
- If you wish to avoid visiting the same file in two buffers under
-different names, set the variable @code{find-file-existing-other-name}
-to a non-@code{nil} value. Then @code{find-file} uses the existing
+@vindex find-file-existing-other-name
+
+ If Emacs should use different buffers when visiting the same file
+under different names, set the variable
+@code{find-file-existing-other-name} to @code{nil}. A non-@code{nil}
+value, which is the default, means @code{find-file} uses the existing
buffer visiting the file, no matter which of the file's names you
specify.
