I noticed some weird behavior of "su" command in shell scripts
running
from cron after upgrade from FreeBSD 8.4 to 10.2.
If I have this in script
su -m www -c 'ls -l'
then I get "TERM: Undefined variable" on the stderr if this script is
run from cron.
It works fine on FreeBSD 8.4
Is it intentional behavior?

I cannot reproduce your problem. I used the following script:
#!/bin/sh
echo "BEGIN TEST"
echo $TERM
su -m www -c 'ls -l'
echo $TERM
echo "END TEST"
crontab is:
* * * * * /root/test.sh
and the result is:
BEGIN TEST

RELEASE-amd64-disc1.iso
-rwxr-xr-x 1 root wheel 90 Nov 21 15:33 test.sh
END TEST
# freebsd-version
10.2-RELEASE-p7
It's a strange. I tried it on another machine which was installed as
10.1 and upgraded to 10.2-p5 - and I got Undefined variable again:
BEGIN TEST
TERM: Undefined variable.

The only workaround I found is adding
export TERM=""
at the top of the script.
