From 53677ef18e25c97ac613349087c5cb33ae5a2741 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Tue, 20 May 2008 16:00:29 +0200 Subject: Big white-space cleanup. This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems.
