 The locale module exposes the C library's gettext interface on systems that
-provide this interface.  It consists of the functions :func:`gettext`,
-:func:`dgettext`, :func:`dcgettext`, :func:`textdomain`, :func:`bindtextdomain`,
-and :func:`bind_textdomain_codeset`.  These are similar to the same functions in

+:func:`!dgettext`, :func:`!dcgettext`, :func:`!textdomain`, :func:`!bindtextdomain`,
+and :func:`!bind_textdomain_codeset`.  These are similar to the same functions in
 the :mod:`gettext` module, but use the C library's binary format for message
 catalogs, and the C library's search algorithms for locating message catalogs.
 
 Python applications should normally find no need to invoke these functions, and
 should use :mod:`gettext` instead.  A known exception to this rule are
 applications that link with additional C libraries which internally invoke
-:c:func:`gettext` or :func:`dcgettext`.  For these applications, it may be
+:c:func:`gettext` or :c:func:`dcgettext`.  For these applications, it may be
 necessary to bind the text domain, so that the libraries can properly locate
 their message catalogs.
