New submission from Sebastian Bank:
ConfigParser parses section lines containing square brackets like '[spam [eggs]
spam]' up to the first instead of the last occurrence of ']' preventing
roundtrips:
>>> s = StringIO()
>>> c1 = ConfigParser()
>>> c1.add_section('spam [eggs]')
>>> c1.write(s)
>>> s.seek(0)
>>> c2 = ConfigParser()
>>> c2.readfp(s)
>>> assert c1.sections() == c2.sections() # fails
Potential fix: change the second line of SECTCRE from r'(?P<header>[^]]+)' to
r'(?P<header>.+?)'.
If the parsing behaviour cannot be changed, the user should at least be warned
about supplying data that breaks the roundtrip.
