From 122f76f574ce260429bfbd11251eed15039e3469 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 23 Sep 2015 13:46:39 -0700 Subject: fsck: exit with non-zero when problems are found After finding some problems (e.g. a ref refs/heads/X points at an object that is not a commit) and issuing an error message, the program failed to signal the fact that it found an error by a non-zero exit status.
