commit d6e2c593180934926fa4cc5b58fdab82b20f5f14

    Fix pre- and post-command-hook errors in term.el
    
    Before this patch, after the terminal process dies the command
    hooks added in term-mode's char mode would produce errors.
    This fix removes these hooks when the process dies.
    * lisp/term.el (term-handle-exit): Remove pre-command-hook and
    post-command-hook because the process is dead.  (Bug#31236)
