OK. I'm not at all interested in carrying maintenance burden for some
software behind closed doors. I could see values in having a more
flexible sparse checkout but this now seems like very tightly designed
for GVFS. So unless there's another use case (preferably open source)
for this, I don't think this should be added in git.git.
