 DESCRIPTION
 	Remove @var{section} from the output.  If the output section
-	becomes empty, remove it from the output bfd.  @var{info} may
-	be NULL; if it is not, it is used to decide whether the output
-	section is empty.
+	becomes empty, remove it from the output bfd.
+
+	This function won't actually do anything except twiddle flags
+	if called too late in the linking process, when it's not safe
+	to remove sections.
