At my end I ran the `readonly` test with the `--keep-failures` flags and found out the following:

So it looks like the readonly status of the annex object got copied between r1 (`tmprepo0`) and r2
(`temprepo1`) at the point of `get` and that prevented the removal of the file during `drop`.
(Btw. I found out that in Msys2/MinGW what is represented as the POSIX readonly mode bits seems
to be really represented by the readonly file attribute and not as readonly permissions/ACLs
on the file. At least that seems to be the default setting. Cygwin on the other hand defaults
to mapping mode bits to ACLs in a rather complex fashion. All of this are just some details
that lie behind what calling out to an external `chmod` binary entails on Windows both above
in my Git Bash session and in git-annex' unit test `test_readonly`.)
