[PATCH v2 2/5] config: make some helpers repo-aware

["Derrick Stolee via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>

As we prepare to add new config helpers to write into a config.worktree,
let's make some existing methods be available for writing to a config
file relative to a repository.
