1.7.2-rc7 bugs

With this example
```python
def f():
    """CC.

    :math:`-`

    :param d: blabla
    :param list(str) l: blabla
    """
```
docformatter inserts a blank space after the second `:` and concatenates the params:
```python
def f():
    """CC.

    :math: `-`
    :param d: blabla :param list(str) l: blabla
    """
```
