[BUG] Failed to parse the value when it is in a new line

### Problem:
Failed to read the value from the given section and option. It gives empty.

Input:
```
[section]
option1 = value1
option2 = value2
option3 =
    value3
```

For the above example `parser.Get("section", "option3")` returns `empty value`.

### Expected:
For the above example `parser.Get("section", "option3")` must return `value3`.
