Hello,

I have the following command:

/usr/bin/git for-each-ref --merged="${GIT_HEAD-HEAD}"
--sort='-taggerdate' --sort='-*committerdate'
--format="%(*committerdate)|%(taggerdate)|%(tag)" refs/tags

I thought this will use: -*commiterdate as a primary key and
-taggerdate as a secondary. According to man page for --sort: "You may
use the --sort=<key> option multiple times, in which case the last key
becomes the primary key."

But that doesn't seem to be the case. I created a repo with a single
commit and created annotated tags on the commit in the following
order:

$ git tag -a -m "foo" B
$ git tag -a -m "foo" C
$ git tag -a -m "foo" A

Yet the order I am getting after running the command is:

Sat May 2 22:10:30 2020 +0200|Sat May 2 22:14:49 2020 +0200|C
Sat May 2 22:10:30 2020 +0200|Sat May 2 22:14:45 2020 +0200|B
Sat May 2 22:10:30 2020 +0200|Sat May 2 22:14:51 2020 +0200|A

Is it a mistake in man pages? Is there any way to sort by multiple keys?

Thank you
