Subject: [PATCH v4 05/19] grep: remove redundant `regflags &= ~REG_EXTENDED` assignments
Date: Tue, 25 Apr 2017 21:05:34 +0000	[thread overview]
Message-ID: <20170425210548.24612-6-avarab@gmail.com> (raw)
In-Reply-To: <20170425210548.24612-1-avarab@gmail.com>

Remove redundant assignments to the "regflags" variable. There are no
code paths that have previously set the regflags to anything, and
certainly not to `|= REG_EXTENDED`.

This code gave the impression that it had to reset its environment,
but it doesn't. This dates back to the initial introduction of
git-grep in commit 5010cb5fcc ("built-in "git grep"", 2006-04-30).
