From a3f71001c30f8927495828da9888bcef86e24035 Mon Sep 17 00:00:00 2001 From: Javier Viguera Date: Tue, 27 Jul 2010 11:13:28 +0200 Subject: [PATCH] find_stray_empty_lines: fix tail "invalid context" error "tail -1" works only with one input file. Using it with multiple input files throws following error on Ubuntu systems: tail: option used in invalid context Adding "-n" makes it work on all cases.
