    [man]: Fix Savannah #51468.
    
    * tmac/an.tmac (SH, SS, B, I, SM, SB): Set input trap with `it` instead
      of `itc` for better Unix Version 7 man(7) compatibility.
    
    Fixes <https://savannah.gnu.org/bugs/?51468>.  Also see discussion at
    https://lists.gnu.org/archive/html/groff/2022-06/msg00020.html et
    sequentia (amid a vigorous bikeshedding of `\&`'s name).
    
    This exposes markup errors in several man pages that use `TP` with `\c`
    and single-font macros.
