Apply a vendor fix for one problem with tagged lists.  From ChangeLog:

2003-05-18  Werner LEMBERG  <wl@gnu.org>
        * tmac/doc.tmac (doc-tag-list): Force horizontal mode after tag
        to make items work which consist only of a tag.

2003-05-17  Werner LEMBERG  <wl@gnu.org>
        * tmac/doc.tmac (doc-tag-list): Don't use \Z to assure that spaces
        aren't stretched in a tag (this can fail with unformatted boxes).
        Instead, insert a break and go back one line.
