Source Control seems not recognizing the error message given by git correctly

Does this issue occur when all extensions are disabled?: Yes

• OS Version: macOS Sequioa 15.0.1

Background: Due to some reasons, I added ProxyCommand to my SSH configuration in order to stablize the connection to GitHub. There's an extra message displayed each time the connection is created.

Connection to ssh.github.com port 443 [tcp/https] succeeded!

Today I was trying to push using the built-in Source Control panel and got this:

This makes no sense. I checked the command output and found that the actual cause is some common misconfiguration.

> git pull --tags origin main
Connection to ssh.github.com port 443 [tcp/https] succeeded!
From ***
 * branch            main       -> FETCH_HEAD
hint: You have divergent branches and need to specify how to reconcile them.
hint: You can do so by running one of the following commands sometime before
hint: your next pull:
hint: 
hint:   git config pull.rebase false  # merge
hint:   git config pull.rebase true   # rebase
hint:   git config pull.ff only       # fast-forward only
hint: 
hint: You can replace "git config" with "git config --global" to set a default
hint: preference for all repositories. You can also pass --rebase, --no-rebase,
hint: or --ff-only on the command line to override the configured default per
hint: invocation.
fatal: Need to specify how to reconcile divergent branches.

So the success connection message is shown instead of fatal: Need to specify how to reconcile divergent branches. in the popup. It worked fine after I, according to the output, specified the reconcilement policy through command line.

Steps to Reproduce:

1. Add ProxyCommand settings to ssh configuration and start the proxy. Example:

Host github.com
	HostName ssh.github.com
	Port 443
	User git
	ProxyCommand nc -v -x 127.0.0.1:PORT %h %p

This step generates the extra message Connection to ssh.github.com port 443 [tcp/https] succeeded! 2. I think any fatal error can reproduce the popup. For the error I encountered:

1. Unset any reconciling policy of git. e.g. git config --unset pull.rebase
2. Do something to produce divergent branches, like committing to the remote repository without local sync.
3. Make changes locally, commit & push to the remote in built-in Source Control panel.
4. This would lead to fatal: Need to specify how to reconcile divergent branches., but the success info is shown instead.
