Thanks; applied to Emacs 28.  One note:

Is this on purpose to test `next-line'?   If it is, this warning should
probably be inhibited:

lisp/progmodes/cperl-mode-tests.el:284:16: Warning: ‘next-line’ is for
    interactive use only; use ‘forward-line’ instead.

If not, forward-line should be used.
