Warning about internal doxygen inconsistency for python packages

In the Ansible package (through Fossies) we get warnings like:
```
lib/ansible/module_utils/facts/virtual/base.py:27: warning: Internal inconsistency: scope for class ansible::module_utils::facts::virtual ::base::Virtual not found!
```
Due to the naming of python the classes in doxygen it is possible that those names will contain reserved names as the path is used in the identification of the class (here `virtual`).
When a `:` is in front of the word it is a class name and no space should be appended.
