From 7aa651a6a4496d848f86de9b1e6b3a003256a01f Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Tue, 13 Nov 2012 17:14:08 -0600 Subject: Reindent to two spaces per level. Remove vi: directives that haven't worked right in years (ubuntu broke its' vim implementation). Remove trailing spaces. Add/remove blank lines. Re-wordwrap in places. Update documentation with new coding style. The actual code should be the same afterward, this is just cosmetic refactoring. --- toys/other/oneit.c | 45 +++++++++++++++++++++------------------------ 1 file changed, 21 insertions(+), 24 deletions(-) (limited to 'toys/other/oneit.c') diff --git a/toys/other/oneit.c b/toys/other/oneit.c index 8bb482da..5bf4e941 100644 --- a/toys/other/oneit.c +++ b/toys/other/oneit.c @@ -1,27 +1,25 @@ -/* vi: set sw=4 ts=4: - * - * oneit.c - tiny init replacement to launch a single child process. +/* oneit.c - tiny init replacement to launch a single child process. * * Copyright 2005, 2007 by Rob Landley .
