sync --content: New option that makes the content of annexed files be transferred. Similar to the assistant, this honors any configured preferred content expressions. I am not entirely happpy with the implementation. It would be nicer if the seek function returned a list of actions which included the individual file gets and copies and drops, rather than the current list of calls to syncContent. This would allow getting rid of the somewhat reundant display of "sync file [ok\|failed]" after the get/put display. But, do that, withFilesInGit would need to somehow be able to construct such a mixed action list. And it would be less efficient than the current implementation, which is able to reuse several values between eg get and drop. Note that currently this does not try to satisfy numcopies when getting/putting files (numcopies are of course checked when dropping files!) This makes it like the assistant, and unlike get --auto and copy --auto, which do duplicate files when numcopies is not yet satisfied. I don't know if this is the right decision; it only seemed to make sense to have this parallel the assistant as far as possible to start with, since I know the assistant works.
