From e3edd6cda410d25082135a6526cf7bfa17b49d8c Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Fri, 6 Mar 2015 16:50:54 -0600 Subject: sed depends on -r to be rightmost flag to simplify the REG_EXTENDED test. (If a flag is 1, you can multiply it by the value you want and get that value else zero without a branch or conditional assignment.) So move -E one to the left so FLAG_r is 1 again, and add a [+Er] suffix instead of testing FLAG_r | FLAG_E in the users. --- toys/posix/sed.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'toys/posix/sed.c') diff --git a/toys/posix/sed.c b/toys/posix/sed.c index dc3c8d91..705ea7bc 100644 --- a/toys/posix/sed.c +++ b/toys/posix/sed.c @@ -7,7 +7,7 @@ * TODO: lines > 2G could signed int wrap length counters.
