Multiline docstring blocks not correctly stripped with INLINE_SOURCES

[overlord624]

When filtering multiline docstrings, the line containing the terminating sequence (""") is included in the generated code fragments from the Doxygen option INLINE_SOURCES. This results in incorrect syntax highlighting.

For example:

def f():
   """
   arbitrary text
   """
   do_stuff()

Will output the following code with the documentation of the function

  """
  do_stuff()
