I like the idea that entries are  ignored unless they end in ".cron".

This does not only allow to install inactive cron scheduled in a file
ending in ".cron.sample", it also lets you rename modified cron tabs
to e.g. ".cron.off" (a convention often used by me).


If the port is re-installed, it is up the administrator to decide
whether a schedule based on a freshly installed ".cron.sample" or
the old ".cron.off" should be enabled.

This would require the deinstall target / tool to rename any cron
entry of the port / package by appending ".off", but that's a minor
change, IMHO.

This might lead to some clutter in ".../cron.d/", but I do not think
that stale files should be automatically removed (even if they were
older than some threshold).
