Yes, I know that the commits can still be recovered
(otherwise this would be a much bigger issue), but 'git
reflog' has never been a necessary part of a workflow, has
it? It's nifty and can be very useful in situations where you
accidentally lost something, but you can hardly call this a
nice workflow or expect people that use submodules to know
about this.
