Related to Duy's new "split chekckout", I just realized that I added
--overwrite-ignore (enabled by default) [1] years ago to allow to out
out of this behavior. We could turn --no-overwrite-ignore by default
on the new command "git switch-branch" to err on the safe side. Then
the user could switch to --overwrite-ignore once they learn more about
gitignore and gitattributes (or the coming "backup log"). I'm not sure
if I really like this, but at least it's one of the options.
