The patch I submitted in <87zhuf3gs0.fsf@evledraar.gmail.com>[1] changed
the behavior for read-tree & checkout & merge etc.
It was an RFC more in the spirit of showing what in our current tests
had to change to spur some discussion.
But I'm very sympathetic to this line of argument. I.e. in my patch I'm
changing the semantics of read-tree, which is plumbing.
What do you think about some patch like that which retains the plumbing
behavior for things like read-tree, doesn't introduce "precious" or
"trashable", and just makes you specify "[checkout|merge|...] --force"
in cases where we'd have clobbering?
This would give scripts which relied on our stable plumbing consistent
behavior, while helping users who're using our main porcelain not to
lose data. I could then add a --force option to the likes of read-tree
(on by default), so you could get porcelain-like behavior with
--no-force.
