Subject: 26.3; rmail-summary-delete-forward: Wrong type argument:
 number-or-marker-p, nil
Date: Fri, 14 Feb 2020 20:19:04 -0500 (EST)

I kept getting the error "Wrong type argument: number-or-marker-p, nil" if I
tried to delete a message immediate after retrieving new messages. I finally
figured out a solution. In `rmail-summary-delete-forward', please change:

      (with-current-buffer rmail-buffer
	(rmail-delete-message)
	(setq del-msg rmail-current-message))

to

      (with-current-buffer rmail-buffer
	(setq del-msg rmail-current-message)
	(rmail-delete-message))

For some inexplicable reason, rmail-current-message becomes nil after
executing `rmail-delete-message' *sometimes*. I'm not sure under what
circumstances it does though, so I can't give you a precise recipe to
reproduce it. Changing the order of these two forms completely fixes this
problem for me though. I would really appreciate it if someone committed this
minor change.

Is the `(rmail-summary-mark-deleted del-msg)' on the following line even
needed? rmail-delete-message calls rmail-summary-mark-deleted. Seems like
duplicate effort. If you get rid of that line, then you don't need the
del-msg variable at all, which would simplify this code considerably and also
eliminate the problem.

OK, that seems like a harmless enough change, even if I'm not an rmail
user, so I've applied it to Emacs 28.
