From 4b340593551217904d794cc0a8db55db89b5b066 Mon Sep 17 00:00:00 2001 From: Martin Stenberg Date: Fri, 9 Mar 2012 22:57:54 +0100 Subject: [PATCH] config: report errors at the EOL with correct line number A section in a config file with a missing "]" reports the next line as 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 by decreasing line number by one for these cases.
