Dear git team,

I have run into a bug where git seems to be adding superfluous tabs to
the end of filenames that contain a space. I have attached the output
of `git bugreport` for your review. Feel free to have a look
https://github.com/trufflesecurity/trufflehog/issues/1060 for
additional context.

Thanks.

Regards,
Diogo Fernandes

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

$ mkdir test
$ cd test
$ git init
$ echo foo > "filename 2"
$ git add "filename 2"
$ git commit -m "test"
$ git log -p | grep "+++" | xxd  # 0x09 is a \t character that is being added to a filename with a space

00000000: 2b2b 2b20 622f 6669 6c65 6e61 6d65 2032  +++ b/filename 2
00000010: 090a                                     ..

What did you expect to happen? (Expected behavior)

$ echo "foo" > filename2
4 git add .
$ git commit -m "test"
$ git log -p | grep "+++" | xxd

00000000: 2b2b 2b20 622f 6669 6c65 6e61 6d65 320a  +++ b/filename2.

What happened instead? (Actual behavior)

A tab character is being appended to filenames.

What's different between what you expected and what actually happened?

A tab character should not be appended to filenames.

Anything else you want to add: No.
