Subject: [PATCH 3/4] merge: make merge.renormalize work for all uses of merge machinery
Date: Sun, 02 Aug 2020 06:33:05 +0000
Message-ID: <08c8080b3196a1bd09bbf20ce705ec5ed5180c34.1596349986.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.825.git.git.1596349986.gitgitgadget@gmail.com>

From: Elijah Newren <newren@gmail.com>

The 'merge' command is not the only one that does merges; other commands
like checkout -m or rebase do as well.  Unfortunately, the only area of
the code that checked for the "merge.renormalize" config setting was in
builtin/merge.c, meaning it could only affect merges performed by the
"merge" command.  Move the handling of this config setting to
merge_recursive_config() so that other commands can benefit from it as
well.  Fixes a few tests in t6038.
