CR position changed in exported patch file subject section

[AMD Official Use Only - General]

Hi guys,

Recently I faced a question that the CR position in the patch is not in line with the git log. Below are the steps to reproduce.

touch aaa git add aaa git commit -m "Add a file to test, make sure that the message is a bit long but in a single line"

D:\Source\CustomerRepoTest\Platform1>git log -3
commit 0c9f8555c55c73fd4e5392c8f8516c389f362d17 (HEAD -> test)

    Add a file to test, make make sure that the message is a bit long but in a single line

We can confirm that the commit message is in a single line in the output of git log command(pls refer to above output).

And use below command to generate a patch file. git format-patch -3 --stdout > exported_3.patch We can observe that the commit message's CR position is changed in the exported patch, the subject section is split to two lines(pls refer to below output).

Subject: [PATCH 3/3] Add a file to test, make make sure that the message is a
bit long but in a single line

--- aaa | 0 1 file changed, 0 insertions(+), 0 deletions(-)

Actually, we want to keep the commit message format(subject section) in the patch same as the git log output. I have tried most of arguments of git format-patch and even upgrade the git version. But no good result is observed.

Could you please help to look at this question? Thanks a lot!
