Description

If you happen to submit an at job from a path that contains one or more spaces, it does not properly quote/escape the path when it writes out the info to /var/spool/cron/atjobs/XXXXXX.a (after expanding the prototype in /etc/cron.d/.proto). E.g.

mkdir "/tmp/dir with spaces"
cd "/tmp/dir with spaces"
echo /bin/true | at now + 5min

If you examine the resulting job, it will contain a line cd /tmp/dir with spaces
which will of course cause 'cd: no such file or directory: /tmp/dir' in the output.

It should just be a matter of escaping the output at usr/src/cmd/cron/at.c:681
