    tmac/e.tmac-u: Rename devtag-related registers.
    
    * tmac/e.tmac-u: Rename registers for clarity.  Unlike other macro
      packages supplied by groff, "me" mostly remains within the AT&T
      2-character name space, accessing extended names selectively through
      `do` and `de1` requests.  The package therefore has no characteristic
      name prefix.
        need_eo_h  -> devtag-needs-end-of-heading
        need_eo_tl -> devtag-needs-end-of-title
        need_tl    -> devtag-needs-title
    
      (@html_check_need_title, sh, EQ): The foregoing registers are
      effectively Booleans, so perform Boolean-style tests on their
      interpolations.
    
    Fixes a second third of <https://savannah.gnu.org/bugs/?42515>.
