Bug Report

[Josh Rampersad <josh.rampersad@voiceflow.com>]

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)

Navigated to a non-default branch of the repo.
I wanted a list of tagged commits for a specific tag pattern relating to a
package in my repo.
Ran the command: `git log origin/master --no-walk --grep='my-package' --tags='*my-package*' --decorate-refs='*my-package*'  --format='format:%ct %H %D'`
The output was as expected with the tags not relating to my-package being filtered out from the output by the decorate-refs option.
I then, wanted to pipe this output to a separate program.


What did you expect to happen? (Expected behavior)

I expected that the piped output would be the same as the output in my terminal.

What happened instead? (Actual behavior)

The filtering I got from the decorate-refs flag was no longer being applied. Thus giving me a bunch of tags I did not want

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

Whether the decorate-refs option worked as expected.

Anything else you want to add:
