You may change the code of the function helpFile() in file SagaAlgorithm.py:

def helpFile(self):
    return  os.path.join(os.path.dirname(__file__), "help", self.name.replace(" ", "") + ".html")

[[https://github.com/qgis/Quantum-GIS/blob/master/python/plugins/sextante/saga/SagaAlgorithm.py#L370]]

For the following code:

def helpFile(self):
    import re
    return  os.path.join(os.path.dirname(__file__), "help", re.sub('[^A-Za-z0-9]+', '', self.name).title() + ".html")

This is to remove invalid characters from the names of the commands and make compactible with SAGA help html files that attached to this request.
