I'm not sure if this is a bug, or if I'm just misunderstanding how to
use `import`. Happy to move this to the forum, if that's more
appropriate.

Importing from a directory special-remote into a nested directory
which contains existing files that are more than 1 level deep tries to
overwrite existing files?
```shell
# Import to level 1, with existing files in level 1 - WORKS
#export import_location=level1 && export existing_file_location=level1
# Import to level 2, with existing files in level 1 - WORKS
#export import_location=level1/level2 && export existing_file_location=level1
# Import to level 2, with existing files in level 2 - DOES NOT WORK
#export import_location=level1/level2 && export existing_file_location=level1/level2
# Import to level 3, with existing files in level 1 - WORKS
#export import_location=level1/level2/level3 && export existing_file_location=level1
# Import to level 3, with existing files in level 2 - DOES NOT WORK
#export import_location=level1/level2/level3 && export existing_file_location=level1/level2
# Import to level 3, with existing files in level 3 - DOES NOT WORK
#export import_location=level1/level2/level3 && export existing_file_location=level1/level2/level3
# Import to level 4, with existing files in level 1 - WORKS
#export import_location=level1/level2/level3/level4 && export existing_file_location=level1
# Import to level 4, with existing files in level 2 - DOES NOT WORK
#export import_location=level1/level2/level3/level4 && export existing_file_location=level1/level2
# Import to level 4, with existing files in level 3 - DOES NOT WORK
#export import_location=level1/level2/level3/level4 && export existing_file_location=level1/level2/level3
# Import to level 4, with existing files in level 4 - DOES NOT WORK
export import_location=level1/level2/level3/level4 && export existing_file_location=level1/level2/level3/level4
mkdir remote-directory
echo "import content" > remote-directory/import-file.txt
mkdir repo
cd repo
git init
git annex init
git annex initremote myremote type=directory directory=../remote-directory encryption=none importtree=yes exporttree=yes
mkdir -p ${import_location}
echo "content" > ${existing_file_location}/existing-file.txt
git annex add --force-large
git commit -m "add existing file to annex"
git annex import master:${import_location} --from myremote
git annex merge myremote/master
```
This is the output of the final scenario:
```shell
$ git annex merge myremote/master
merge myremote/master
error: The following untracked working tree files would be overwritten by merge:
level1/level2/level3/level4/existing-file.txt
Please move or remove them before you merge.
Aborting

git-annex: merge: 1 failed

Running this after encountering the situation above also causes
strange things to happen on the `myremote/master` branch:
```shell
git annex import master:${import_location} --from myremote
git annex import master:${import_location} --from myremote
git annex import master:${import_location} --from myremote
git annex import master:${import_location} --from myremote
```
The `myremote/master` branch appears to be stuck in some sort of loop,
trying to remove and add the files over and over?
