[gobject-introspection] Update doc comments.

[Johan Bilien <jobi src gnome org>]

commit 50dd263dbe16ecf8e81c3f674d23cb086f79ca7e
Author: C. Scott Ananian <cscott litl com>
Date:   Tue May 5 13:06:37 2009 -0400

    Update doc comments.
    
    The enumeration values cited here were out of date.  Rewrite to eliminate
    the explicit mention of the enumeration value, to prevent it from
    drifting out of date again in the future.
