Re: [1.8.0] Recursively checkout, merge and reset populated submodules

Risks:
The commands might run longer, for those users who use submodules
to gain performance by putting large and/or many files into
submodules this may be unacceptable.

Nobody would object to make this facility available via config, I think,
but I suspect that it is way too premature to decide which way should
eventually be the default at this point.

My recommendation is to ease this in as an optional feature you can easily
turn on with a config, let people try it for a few release cycles and then
if we reach the concensus that this should be on by the default, start the
usual "warn and tell how to keep the old behavior" one cycle before 1.8.0
(or 1.9.0 if we end up not having enough cycles before 1.8.0).
