From fdb347f7fd6c36b270a8c571cbe9a124a281b2b5 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Wed, 18 Nov 2015 16:57:47 +0100 Subject: [PATCH] lnstat: fix header displaying mechanism The algorithm depends on the loop counter ('i') to increment by one in each iteration. Though if running endlessly (count==0), the counter was not incremented at all. Also change formatting of the header printing conditional a bit so it's hopefully easier to read.
