That is always sad to hear, when work is lost.

However, I personally wonder if this is a bug or not.
First, Git is told to track a file called README/README
Then the file is removed, without telling Git.
And a new, unkown file appers on disk (which collides with the name
of the directory)

Using this sequence could have told Git, what is going on:
git mv README/README README2
rmdir README
git mv README2 README

(a temporary branch may be checked out, with the option
 to merge-squash the final result)


An other alternative could be to tell `git stash` to care
about untracked file(s):

git stash -u
git stash pop

Which will refuse to apply the stash.

A third alternative could be to keep the file inside an
editor, to have the content still available.

However, it would/could be nice, if files are not simply deleted,
but saved into a "lost+found" folder, or a wastebasket kind of thing.

But which files ?
Those that are untracked ?
They may be important (local config files, passwords, help scripts, ...)
or not (.o files from a C compiler).

In some older discussions they had been named "precious" files.
But, as far as I remember, there was no easy solution.
In that sense I don't have a better answer.
Others may have.

Thanks for reporting, it make me read [1] and come to the conclusion
that it is sometimes safer to checkout out a temporary branch, commit
everything and clean up later, rather than relying too much on
`git stash`
