Empty python comment gives problems
In case we have an empty python comment like: `"""""""` (i.e. 6 double quotes) doxygen will crash in the pyscanner.l version of `stripIndentation`.
```
class Translator(nodes.NodeVisitor):
""""""
## the var
words_and_spaces = re.compile(r'\S+| +|\n')
```
In case of an empty comment we should not call `stripIndentation` and not place `\verbatim` / `\endverbatim` around the empty comment (the later would give an non-understandable empty comment block).
An empty comment should be handled as no comment.
Found by Fossies whilst generating documentation for Mercural 5.5).
