[PATCH v2 2/4] config: fix config scope enum

Message-ID: <e8e05f39407365a1bf5008820267d362e0cbffd6.1578565001.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.478.v2.git.1578565001.gitgitgadget@gmail.com>

From: Matthew Rogers <mattr94@gmail.com>

Previously when iterating through git config variables, worktree config and local config were both considered "CONFIG_SCOPE_REPO". This was never a problem before as no one had needed to differentiate between the two cases.

Additionally we rename what was CONFIG_SCOPE_REPO to CONFIG_SCOPE_LOCAL to reflect its new, more specific meaning.

The clients of 'current_config_scope()' who cared about CONFIG_SCOPE_REPO are also modified to similarly care about CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.
