Hello. 👋
I'm seeing strange issues with log/listing trailer information for commits and tags and I think I'm experiencing a bug where when I attempt to list commits and tags with specific trailer keys, I get new lines showing up in my output.
Here's my steps to recreate using a simple Bash script:
```
mkdir demo
cd demo
git init
touch one.txt
git add .
git commit --message "Added one" --trailer Milestone=patch --trailer Issue=111
git tag 0.0.0 --message "Version 0.0.0" --no-sign --trailer Files:1 --trailer Duration:1
touch two.txt
git add .
git commit --message "Added two" --trailer Milestone=patch --trailer Issue=222
git tag 0.0.1 --message "Version 0.0.1" --no-sign --trailer Files:1 --trailer Duration:1
```
Notice that I'm using trailers for my commits *and* tags. Here's what my git log looks like:
```
git log --pretty=format:"%h %an% %s %d %cr. %(trailers:key=Milestone) %(trailers:key=Issue)"
```
The above produces this output:
08a07b717bef Brooke KuhlmannAdded two (HEAD -> main, tag: 0.0.1) 5 minutes ago. Milestone: patch
Issue: 222
01c4c182c85e Brooke KuhlmannAdded one (tag: 0.0.0) 5 minutes ago. Milestone: patch
Issue: 111
...and if I list my tags using this command:
```
git tag --list \
--format="%(refname:short) %(taggerdate:short) %(taggername) %(subject) %(trailers:key=Files) %(trailers:key=Duration)"
```
...I get this output:
0.0.0 2024-09-06 Brooke Kuhlmann Version 0.0.0 Files: 1
Duration: 1
Files: 1
Duration: 1
0.0.1 2024-09-06 Brooke Kuhlmann Version 0.0.1 Files: 1
Duration: 1
Files: 1
Duration: 1
Notice, when logging trailer information for commits and tags, I get unexpected new line characters showing up in the output. I expect to see all information printed on the same line without any new lines showing up.
Also, I want to point out that when listing tag trailers, I get the "Duration" key showing up twice. I'm not sure if that's related or not but seems like very weird behavior.
