I dunno - I can tell zsh to are-you-sure me about an `rm -rf *`, git seems like it should be able to do similarly. Or, as Mercurial does, back up overwritten files to .bak.

These are pretty light asks.

The sole purpose of git checkout -- file is to overwrite the file you explicitly listed. There should not be a confirmation by default.
