My understanding is that a preferred content value of "anything" (or
equivalently the standard group "backup") should consider deleted
files from a remote as wanted. I'm not a heavy user of preferred
content myself, so this understanding is based primarily off of the
[preferred_content/standard_groups][0] documentation saying
```
### backup
All content is wanted. Even content of old/deleted files.
`anything`
```
At least with the scenarios I've constructed, I haven't been able to
find a case where old files are considered. As an example:
[[!format sh """
cd "$(mktemp -d ${TMPDIR:-/tmp}/gx-XXXXXXX)"
git init a
(
cd a
git annex init a
>foo && git annex add foo && git commit -m"add foo"
git rm foo && git commit -m"delete foo"
)
git clone a b
(
cd b
git annex init b
git annex wanted . anything
git annex sync
set -x
git show git-annex:uuid.log
git show git-annex:preferred-content.log
git annex find --want-get
git annex get --auto
git annex unused
)
"""]]
```
[...]
+ git show git-annex:uuid.log
17fae615-a90b-405a-85c2-9d0f28246bdf a timestamp=1586190820.385256186s
1f0ad7d6-31ba-4d7e-a2e6-ab6acb3338c9 b timestamp=1586190820.750487084s
+ git show git-annex:preferred-content.log
1f0ad7d6-31ba-4d7e-a2e6-ab6acb3338c9 anything timestamp=1586190820.867633471s
+ git annex find --want-get
+ git annex get --auto
+ git annex unused
unused . (checking for unused data...) ok
```
The output above is with 8.20200330, but I saw the same result when I
tried with 7.20190819.
I haven't been able to think of another way to interpret "Even content
of old/deleted files", so I think at least this is a documentation
bug.

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
Yes. Thank you! :>
