This is a regression in master (emacs-26 is ok), as reported in [1]:
when I open term or ansi-term there is always a % character at the
end of every command i execute in term.
Stated in terms of tests/lisp/term.el, the following fails:
(ert-deftest term-line-wrapping-then-motion ()
"Make sure we reset the line-wrapping state after moving cursor.
A real-life example is the default zsh prompt which writes spaces
to the end of line (triggering line-wrapping state), and then
sends a carriage return followed by another space to overwrite
the first character of the line."
(let* ((width 10)
(strs (list "x" (make-string (1- width) ?_)
"\r_")))
(should (equal (term-test-screen-from-input width 12 strs)
(make-string width ?_)))))
Patch to follow.
