Add a 'force' option for non-interactive crontab removal

[sam_samgwydir.com]

Summary

While converting a user provisioning tool from use in linux to FreeBSD it turned out crontab -r was interactive (requiring 'y' to remove). This diff adds a '-f' option to force crontab to be non-interactive.

Test Plan

Tested by adding a test user, creating a crontab for them and attempting to remove it with a without '-f' set.

Spacing between 'int' and 'fflag' looks off relative to other variables nearby.

Added more context.

Also fixed spacing before 'fflag'

[sam_samgwydir.com]

Fixed spacing. There was an extra space that I did not account for.

Do you have a commit bit, or do you need me to commit this for you? Thanks!

In general, bump .Dd to the date you changed the manual page.

I see. You could also workaround this by running crontab ... < /dev/null. I still like your -f flag, though.

[sam_samgwydir.com]

Fixed date in manpage and no I don't have a bit -- if you could commit that would be great.

[sam_samgwydir.com]

Diff was broken -- now fixed.

This implies that -f is used instead of one of the other arguments. I suggest

{
.Fl l |
.Fl r Op Fl f
|
.Fl e
}

This should probably not be a separate item, since it is only used with -r.

Add
.Fl f
to force the removal without a prompt for confirmation.

[sam_samgwydir.com]

Fixed man page according to feedback. Also fixed usage() to reflect those changes.

Yeah we were piping in yes but it wasn't until I got into the code I saw there was some way to make it non-interactive, but it's undocumented.

This patch is ready to go now -- if someone could commit it that'd be perfect.
