From e0f617699f7f1dfa1e56ded54bb1d70fd91c225e Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Thu, 13 Sep 2018 15:01:45 +0200 Subject: [PATCH] head: add test case for negative -n invocation Commit 2da9724b56169f00bd7fb6b9a11c9409a7620981 broke 'head -n -1' and was later reverted with 0d598ab9f03dbf320f7b81c05e4a94cb303dfbc7. This commit adds a test case to avoid future breakage.
