Um, how should I do this?  I tried (I've also added
@anchor{update-file-autoloads} below @findex update-file-autoloads):

    the corresponding list of files to load for it.  Entries to this
    mapping are added by calls to @code{register-definition-prefixes}
    which are generated automatically (@pxref{update-file-autoloads,
    @code{update-file-autoloads}}).  Files which don't contain any

But it looks rather strange, it adds an extra period.

    corresponding list of files to load for it.  Entries to this mapping
