From b3b3f60bb672d23b9db1582395a1d29561cb79ef Mon Sep 17 00:00:00 2001 From: Matthieu Moy Date: Thu, 7 Aug 2014 04:59:13 -0700 Subject: [PATCH] config.c: fix accuracy of line number in errors If a callback returns a negative value to `git_config*()` family, they call `die()` while printing the line number and the file name. Currently the printed line number is off by one, thus printing the wrong line number. Make `linenr` point to the line we just parsed during the call to callback to get accurate line number in error messages.
