I finally figured it out. Adding this to sshd_config did the trick:
BatchMode yes
I saw it suggested as a command line option, but didn't realize it
could be specified in the config file. Use of that option in this
manner so far doesn't seem to have had any adverse effect on normal
operation, and it did fix the controlling-tty problem with cron.
Hope this helps some of you; I know I'm not the only one who's
wrestled with this.
