[issue28249] doctest.DocTestFinder reports incorrect line numbers with exclude_empty=False

[Clément]

New submission from Clément:

Line numbers reported by the doctest module are wrong when a function does not 
include a docstring.  With the attached example file, running

python -c "import doctest, example; 
print(doctest.DocTestFinder(exclude_empty=False).find(example))"

produces

[,
 ,
 ,
 ]

whereas if one uncomments the docstrings of a and c the output is

[,
 ,
 ,
 ]

This bug is due to this line in doctest:

lineno = self._find_lineno(obj, source_lines)

The documentation of _find_lineno says this:

def _find_lineno(self, obj, source_lines):
"""
Return a line number of the given object's docstring.  Note:
this method assumes that the object has a docstring.
"""

This assumption is violated by the call listed above, because of the 
exclude_empty=False parameter to DocTestFinder().

I guess lineno should just be None for all methods that do not have a docstring?
