scheduling.cpp: fix launchd "no need to update"
scheduling.cpp: fix launchd "no need to update"

Sometimes I wonder if I go overboard with automated testing.  Am I spending
hours on compile and run-time tests just so I can procrastinate dealing with
program bugs or new features?

The answer is clearly "no".  Almost every time I think "oh, this is a really
simple change", something gets messed up.

(I can't think of a sensible way to automatically test the launchd scheduling
code, though, since I can't see a way to tell launchctl "pretend that this
custom directory is just like ~/Library/LaunchAgents.  I think I'd have to use
container or virtualized OS (and the latter isn't allowed by the MacOS X
license), and that's a lot of work to test such a small file.  I'll muddle on
for now.)
