I just did this
and had no result. If this really is supposed to work, then I suspect that my terminal (Cygwin) might be bugged. Whenever I open crontab -e, I have to mash the keyboard for a bit before what I type comes visible, and if I try to paste code, then only the latter part of the code will be pasted. For example, when pasting
What shows up is
and there is a red alert in the bottom saying
Also, only occosionally when I push the Escape button I get to go on to type :wq to exit crontab -e. Usually when I press Esc, the code will just copy/paste itself some 20-30 times instead. There's also some other strange stuff going on, like when I use the arrow keys; sometimes it makes the "cursor" - the line that shows where I type - move, like it should, and other times it makes the letter A,B,C and D appear on the line above or below the code. This doesn't make much sense to me, but eventually I always get the code I want and I'm able to leave crontab, like now. As you can see, the code is as it should be. but maybe there's some invisible strange stuff going on here, messing up my crontab/tar scheme?

I have the following crontab entry.

bcrontab
bcrontab(1) General Commands Manual bcrontab(1)NAME
bcrontab - Manage users crontab files
SYNOPSIS
bcrontab [ -u user ] file
bcrontab [ -u user ] { -l | -r | -e }
DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory.
OPTIONS -u user
Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running
as either root or the same user ID as the named user.
-l List the cronab crontab to standard output.
-r Remove the user's crontab.
-e Edit the current crontab.
ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab.
EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used.
BCRON_SOCKET
The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool.
LOGNAME
USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not
used.
FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current
crontab.
