From dbb6a4ada6c6c1065b62313127ff032196e9d232 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 23 May 2009 13:45:26 +0200 Subject: [PATCH] grep: fix word-regexp at the beginning of lines After bol is forwarded, it doesn't represent the beginning of the line any more. This means that the beginning-of-line marker (^) mustn't match, i.e. the regex flag REG_NOTBOL needs to be set. This bug was introduced by fb62eb7fab97cea880ea7fe4f341a4dfad14ab48 ("grep -w: forward to next possible position after rejected match").
