That won't work, as it respects the stat information. So does --really-refresh. AFAIK, there isn't a way to tell update-index to ignore start information, short of blowing away the index entirely, and doing a read-tree to repopulate it.

I'm curious what this use case is, and whether it would be acceptable to update something like ctime on the files to make them stat-dirty to git.
