This function creates a new empty section called @var{name} and attaches it
to the end of the chain of sections for the BFD supplied. An attempt to
-create a section with a name which is already in use, returns the old
-section by that name instead.
+create a section with a name which is already in use, returns NULL without
+changing the section chain.
