How does this garbage thing interact with "git clean -x"? My
interpretation of this flag/attribute is that at version 3.0 by
default all ignored files are _not_ garbage, so "git clean -x" should
not remove any of them. Which is weird because most of ignored files
are like *.o that should be removed.
I also need to mark "precious" on untracked or even tracked files (*).
Not sure how this "garbage" attribute interacts with that.
(*) I was hoping I could get the idea [1] implemented in somewhat good
shape before presenting here. But I'm a bit slow on that front. So
yeah this "precious" on untracked/tracked thingy may be even
irrelevant if the patch series will be rejected.
