When exporting the following code block using indentation, it is not
possible to know where the source code ends and the results of
evaluation starts.

```sh
echo "echo ab"
echo "seq 1 2"
```

```
echo ab
seq 1 2
```

The language of the following code block will be `sh` because `dash`
doesn't belong to `org-md-lang-export`

```sh
result=0

for i in $(seq 1 5)
do
  for j in $(seq 1 5)
  do
    result=$((result + i + j))
  done
done

echo "$result"
```

```
150
```

The language of the following code block will be the same as the one
used in Org Mode because `R` doesn't belong to `org-md-lang-export`

```R
data(Loblolly)

max(Loblolly $ height)
```

```
