Howzabout this:

I mod 'crontab -l' so that it doesn't output the extra header iff
CRONTAB_NOHEADER is defined. People can modify their scripts to

CRONTAB_NOHEADER=Y crontab -l

Later, I'll make the new behaviour the default. The advantage is
that we get read of the sed call immediately, and people can set
CRONTAB_NOHEADER in their login scripts and get the new behaviour.

None of this will happen until after jan 1, as I'm trying to get a libc6
release of cern-httpd out before I go on vacation...
