A similar recipe without evil:

M-x term
"/bin/bash" ;; I happen not to have zsh installed at the moment
Hit RET a few times so there is somewhere to move.
C-c M-x eval-expression RET (previous-line) RET
See cursort move up, and then move back to the prompt.

Seems to be on purpose, caused by this code, introduced in [1: 0d8e4f45d6]:

    ;; Don't allow changes to the buffer or to point which are not
    ;; caused by the process filter.
    (when term-char-mode-buffer-read-only
      (setq buffer-read-only t))
    (add-hook 'pre-command-hook #'term-set-goto-process-mark nil t)
    (add-hook 'post-command-hook #'term-goto-process-mark-maybe nil t)

Agreed, this is pretty much working as intended.

Thanks. That’s unfortunate but I’ll live. :)
