I just checked out the super-project:

  git clone --recursive http://github.com/boostorg/boost.git modular-boost

It actually said:

  Submodule path 'libs/program_options': checked out
'fb4f36f3eecbef1e3b4ace5b263e01d56e42d5c7'

But after these commands I saw the newer revisions:

  cd modular-boost/libs/program_options
  git checkout master
  Switched to branch 'master'

  git log -1
  commit 9d7c9875265ec7fec03aabf18e3d53c3e5e1a46c

    Remove tabs.

I'm not sure what the "Submodule" line means, but it seems the
repository is cloned with the newer revisions. Maybe it just doesn't
checkout the latest revision by default. In that case I'd like it to
be fixed.
