I have an issue with git and signing commits with GPG subkey.
My setup:
- master key used for certification only
- subkey for my main workstation
- subkey for my mobile workstation (a notebook).
Both subkeys are used for signing only.

I've configured git to use my specific subkey however it does not work: git config --global user.signingkey = KEYID. Every commit is being signed using the newest subkey. I've verified the same behavior on three systems (although with the same setup). I've tried to use --gpg-sign=KEYID flag, but it does not work either.

Environment:
OS: Archlinux
Shell: ZSH
GPG: 2.2.4
Git: 2.15.1.
Is there any other info I shall provide?
