Subject: [PATCH 2/5] grep: remove redundant grep pattern type assignment

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Wed, 28 Jun 2017 21:58:06 +0000

Remove a redundant assignment to extended_regexp_option to make it
zero if grep.extendedRegexp is not set. This is always called right
after init_grep_defaults() which memsets the entire structure to 0.

This is a logical follow-up to my commit to remove redundant regflags
assignments[1]. This logic was originally introduced in [2], but as
explained in the former commit it's working around a pattern in our
code that no longer exists, and is now confusing as it leads the
reader to think that this needs to be flipped back & forth.

2. b22520a37c ("grep: allow -E and -n to be turned on by default via
   configuration", 2011-03-30)
