Thanks for the feedback. Fixed the code and added two test cases.
New commit description and patch follows.
fix incorrect line number report for bad config
A section in a config file with a missing "]" reports the next line as being
bad, same goes to a value with a missing end quote.
This happens because the error is not detected until the end of the line, when
line number is already increased. Fix this issue by decreasing line number by
one for these cases.
