Hi all,

I'm a developer on the Git Extensions project [1] and am looking at an
issue parsing the output of `git log` in that application.

Some investigation suggests that a certain combination of arguments causes
multiple consecutive null bytes between rows, where I would ordinarily
expect one.

Passing -z with --name-only causes double nulls.

$ git log -z --pretty=format:"%H" --name-only | grep -obUaP "\x00\x00" | wc
-l
8994
$ git log -z --pretty=format:"%H" | grep -obUaP "\x00\x00" | wc -l
0

We can work around this issue, but I would like to understand if it's a bug
or if there's some information to be gleaned here.

$ git --version
git version 2.18.0.windows.1

Many thanks,

Drew
