Failed to install a module from svn if verbose mode is on

[devsagul]

Description

Running pip3 install -v svn+ssh://this.url.does.not.exist fails because it tries to call svn checkout '' --force-interactive svn+ssh://this.url.does.not.exist <tmp-dir> which fails, due to argument '' not being a valid URL for checkout.

The bug was introduced in 22.0.0 while making it possible to propagate verbose mode to the underlying tools.

Expected behavior

pip3 install -v svn+ssh://this.url.does.not.exist should fail, because this.url.does.not.exist is not an existing URL for a svn repo, like in non-verbose mode:

Running command svn checkout --quiet --force-interactive svn+ssh://this.url.does.not.exist <tmp-dir>
  svn: E170013: Unable to connect to a repository at URL 'svn+ssh://this.url.does.not.exist'

pip version

22.0.4

Python version

3.10.2

OS

linux

How to Reproduce

1. Run python3 -m pip install --upgrade pip==22.0.4
2. Run python3 -m pip install -v svn+ssh://this.url.does.not.exist

Output

$ python3 -m pip install --upgrade pip==22.0.4
Requirement already satisfied: pip==22.0.4 in ./.venv/lib/python3.10/site-packages (22.0.4)
$ python3 -m pip install -v svn+ssh://this.url.does.not.exist
