    link: don't escape the anchor
    
    The previous commit broke searching, as g_filename_to_uri() actually escapes the
    anchor symbol used to specify sections within a file. Fix the issue by keeping
    the anchor before building the URI with g_filename_to_uri(), and append it
    afterwards.
