Given a regular expression match from `_EXAMPLE_RE` (`m`),
return a pair `(source, want)`, where `source` is the matched
example's source code (with prompts and indentation stripped);
and `want` is the example's expected output (with indentation
stripped).
`name` is the string's name, and `lineno` is the line number
where the example starts; both are used for error messages.
>>> def parseit(s):
... p = LongFormDocTestParser()
... return p._parse_example(p._EXAMPLE_RE.search(s), '<string>', 1)
>>> parseit('>>> 1\n1')
('1', {}, '1', None)
>>> parseit('>>> (1\n... +1)\n2')
('(1\n+1)', {}, '2', None)
>>> parseit('.. run:\n\n test1\n test2\n')

Divide the given string into examples and intervening text,
and return them as a list of alternating Examples and strings.
Line numbers for the Examples are 0-based. The optional
argument `name` is a name identifying this string, and is only
used for error messages.
