Subject: mail(1) segfaults if thread commands are used in ~/.mailrc

NetBSD x202e.localdomain 9.99.92 NetBSD 9.99.92 (MYKERNEL) #0: Mon Dec 13 03:43:43 UTC 2021 bld@x202e.localdomain:/usr/obj/usr/src/sys/arch/amd64/compile/MYKERNEL amd64
>Description:
Most of the thread-related commands (thread, sort, reverse, ...) cause a
segfault if they're included in ~/.mailrc:
$ echo "sort rdate" > newmailrc
$ mail -r newmailrc
Segmentation fault (core dumped)
$
>How-To-Repeat:
As above.
>Fix:
Make the `thread' commands interactive-only (however, commands like `sort'
or `reverse' seem useful if included in ~/.mailrc).
