Subject: [PATCH] fix incorrect line number report for bad gitconfig

A .gitconfig section with a missing "]" reports the next line as beeing 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.
