From e321180ed3e22120e30bb350a5adecbe959e1241 Mon Sep 17 00:00:00 2001 From: Alex Riesen Date: Thu, 28 Aug 2008 19:15:33 +0200 Subject: [PATCH] Remove calculation of the longest command name from where it is not used Just calculate it where it is needed - it is cheap and trivial, as all the lengths are already there (stored when creating the command lists).
