Subject: [PATCH] Respect `ZDOTDIR` environment variable iff set (#49913)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When `ZDOTDIR` is set, `zsh` reads its configuration from that directory
instead of the user’s `$HOME` directory.

| Setup | `ZDOTDIR` set? | Script writes to | Zsh reads from | Match? |
|---|---|---|---|---|
| XDG + `ZDOTDIR` | ✅ | `$ZDOTDIR/.zshrc` | `$ZDOTDIR/.zshrc` | ✅ |
| XDG without `ZDOTDIR` | ❌ | `$HOME/.zshrc` | `$HOME/.zshrc` | ✅ |
| No XDG at all | ❌ | `$HOME/.zshrc` | `$HOME/.zshrc` | ✅ |
