I agree that the current synopsis is incorrect, but I think it shouldn't
mention line movement at all.
Ibuffer mark commands do not always change line (e.g. when point is on a
filter group name), and the docstring of ibuffer-mode does not describe
any other marking commands as moving line, so it would be inaccurate and
inconsistent to do so for ibuffer-unmark-backward. The synopsis need
only refer to the command's key binding and general purpose; the rest
can be left to its docstring.
So how about the following instead?

Subject: [PATCH] Fix ibuffer-unmark-backward synopsis
* lisp/ibuffer.el (ibuffer-mark-region-or-n-with-char): Fix
indentation.
(ibuffer-mark-interactive): Remove optional third argument of
internal subroutine considered deprecated since Emacs 24.4.
(ibuffer-mark-for-delete-backwards): Don't use it.
(ibuffer-mode): Minor copy-edits. Fix synopsis of
ibuffer-unmark-backward. (bug#35572)
