Then, we are getting back to point #0, we don't have universally way
to specify stdin as input file for crontab(1) and "crontab -e" is
optional.

Perhaps, FreeBSD needs to carry this patch downstream; or
we will invent new preprocessor, let's say CRONTAB_DASH_IS_STDIN
which is defined in FreeBSD, and another config, let's say
crontab.dashIsStdin (in order to allow users swap their default
cron) which is default to 1 if CRONTAB_DASH_IS_STDIN is defined,
and 0 otherwise.  So, everyone will be happy.  Thought?
