Description of problem:
If you do a crontab -l it prefixes the user crontab with extra comments:

# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.20699 installed on Sat Sep  6 15:24:23 2003)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)

After several iterations of
 crontab -l > ctab
 vi ctab
 crontab ctab
you end up with a lot of extra headers.

That header is supposed to be in the cron file in /var/spool/cron, but NOT be
reported to the user.  Especially since there's no reason for them to not edit a
file they create via crontab -l.

Version-Release number of selected component (if applicable):
vixie-cron-3.0.1-74

How reproducible:
Always

Steps to Reproduce:
1. create user crontab
2. crontab -l

Actual Results:  Extra headers reported

Expected Results:  No headers... only user comments.
