Message-ID: <pull.1274.git.git.1654637044966.gitgitgadget@gmail.com>

From: Glen Choo <chooglen@google.com>

Test that "git config --show-scope" shows the "worktree" scope, and add it to the list of scopes in Documentation/git-config.txt.

"git config --help" does not need to be updated because it already mentions "worktree".

    config: document and test the 'worktree' scope
    
    While I was digging through the docs on config scopes for
    discovery.bare, I noticed that Documentation/git-config.txt doesn't
    mention the 'worktree' scope, but the usage string does.
    
    One might assume that since we have CONFIG_SCOPE_WORKTREE, the omission
    from Documentation/git-config.txt is obviously accidental. But, when we
    first added "--show-scope" in 145d59f (config: add '--show-scope' to
    print the scope of a config value, 2020-02-10), we noted that
    'submodule' would never be output from "--show-scope", even though
    CONFIG_SCOPE_SUBMODULE exists.
    
    This patch adds a test that shows "git config -l --show-scope" can
    indeed output 'worktree', and adds the 'worktree' scope to
    Documentation/git-config.txt.
    
    This does not conflict with gc/bare-repo-discovery.
