[Bug-mcron] Reloading the user's jobs

[Ludovic Courtès]

Hello,

When running `mcron' as a user, it is tempting to run "mcron -d" so that
`mcron' remains out of sight.  However, when adding new jobs or
modifying existing jobs, the recommended way is to run `mcron', which
has the unfortunate effect of spawning a new `mcron'.

It would be nice if running `mcron' would instead wake up the already
running `mcron' if there is one, telling it to reload the job list.

What do you think?

Thanks,
Ludo'.
