Err, TERM=linux also causes errors when tests are run via cron.
Reset TERM=dummy.
Workaround is to do a CRON=running from within the cron job and only set
TERM=dummy when not run via cron.
The TERM=dummy setting causes backspaces (^H) to appear in stdout when running
from cron. Changing to TERM=linux should fix the ^H's in stdout AND the bug of
`meta_on' or `meta_off' escape sequences in stdout, caused by a bug in
supposedly libreadline5:

Steps to reproduce output of ^H with TERM=dummy:
$ batch
warning: commands will be executed using /bin/sh
at> ./runUnit _known_hosts_real.exp --debug < /dev/tty40
at> ^D
NOTE: You need to connect a terminal (< /dev/tty..) to the test suite
when running from cron. See also doc/testing.txt, "Running tests via
cron".
`_known_hosts_real' will add hosts from HOSTFILE (compgen -A hostname), unless
`COMP_KNOWN_HOSTS_WITH_HOSTFILE' is set to an empty value.
To run the unit tests:
$ cd test && ./runUnit _known_hosts_real.exp
