Testing:
>>> text = s = ''' # Dedent demo
No indent
Three space indent
\tOne tab indent
\t\tThree space, two tab indent
\t \tOne tab, two space, one tab indent with two tabs here >\t\t<'''
>>> print text
print s
# Dedent demo
No indent
Three space indent
One tab indent
Three space - two tab indent
One tab - two spaces - one tab indent with two tabs here >
<
>>> for line in text.splitlines (): print Dedent.sub ('', line)
# Dedent demo
No indent
Three space indent
One tab indent
