From c14daa4845ff2ec0d27807fa50f9fac1ca4d6462 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Sat, 22 Oct 2011 19:44:40 +0200 Subject: [PATCH] make the sample pre-commit hook script reject names with newlines, too The sample pre-commit hook script would fail to reject a file name like "a\nb" because of the way newlines are handled in "$(...)". Adjust the test to count filtered bytes and require there be 0. Also print all diagnostics to standard error, not stdout, so they will actually be seen.
