 @end group
 @end example
 
+In some cases, a leading @samp{..} can remain in the output:
+
address@hidden
address@hidden
+(expand-file-name "../home" "/")
+     @result{} "/../home"
address@hidden group
address@hidden example
+
+This is for use with filesystems that have the concept of a
+``superroot'' above the root directory @file{/}.  On other filesystems,
address@hidden/../} is interpreted exactly the same as @file{/}.
+
 Note that @code{expand-file-name} does @emph{not} expand environment
 variables; only @code{substitute-in-file-name} does that.
