Last week I typed "crontab -" (missed the "e" for -e)  and then without 
realizing what happened Ctrl-C didn't work, typed Ctrl-D.  Argh. Lost 
around 20 crontabs which were in a directory I didn't backup. Luckily I 
had a syslog file with my recent jobs to recreate it, but lost all my 
comments and commented-out entries (for over ten years).
