[Bug 1938924] [NEW] Update contrab(5) manpage to match new behaviour

[Graham Inggs]

Public bug reported:

>From LP: #1779767 comment 13:

In crontab(5) in cron 3.0pl1-136ubuntu2 the manpage is now wrong. It
says:

> Several environment variables are set up automatically by the cron(8) daemon.
> […] PATH is set to "/usr/bin:/bin". HOME, SHELL, and PATH may be overridden
> by settings in the crontab […]

and also

> On the Debian GNU/Linux system, cron supports the pam_env module, and loads
> the environment specified by /etc/environment and /etc/security/pam_env.conf.
> It also reads locale information from /etc/default/locale. However, the PAM
> settings do NOT override the settings described above nor any settings in the
> crontab file itself.  Note in particular that if you want a PATH other than
> "/usr/bin:/bin", you will need to set it in the crontab file.

These should be fixed I think. There might be other spots that I didn't notice
yet too.
