Subject: grep: remove redundant and verbose re-assignments to 0
X-Git-Tag: v2.14.0-rc0~4^2~2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b07ed4e532fa9492a53b7b510c45efd671f468a8;p=git-core%2Fgit.git

grep: remove redundant and verbose re-assignments to 0

Remove the redundant re-assignments of the fixed/pcre1/pcre2 fields to
zero right after the entire struct has been set to zero via
memset(...).

See an earlier related cleanup commit e0b9f8ae09 ("grep: remove
redundant regflags assignments", 2017-05-25) for an explanation of why
the code was structured like this to begin with.
