Commands: Set configuration file (for tests) #474
Description
Problem
Issue #472 requires session-scoped fixtures.
Currently, we use set_home, gitconfig, and hgconfig to monkeypatch.setenv $HOME, pointing it to a temporary directory with user-specific configuration files. This ensures all subsequent git and hg commands automatically load these configurations.
However, monkeypatch.setenv doesn't work with function-scoped fixtures.
