[PATCH 0/4] repo: add support for path-related fields

Hi!

This patch series adds support for path-related fields in repo-info, based on what we already have in git-rev-parse:

1. The two first patches moves the path formatting used by git-rev-parse to
   path.c. This will allow us to reuse this code in git-repo-info
2. The second patch add a new flag --path-format to git-repo-info, similar to
   the flag of git-rev-parse with the same name
3. Add the new field `path.toplevel` as a proof of concept.

This arises from the fact that I didn't know what should be the default behavior of git-repo-info when dealing with paths. Some ideas were:

1. Add --path-format, just like we have in git-rev-parse
2. Use what rev-parse uses by default
3. Add keys for both relative and absolute formats

In this case, I'm using 1, but I'm not sure if it's the best option. One downside that I see here is that git-repo-info won't be able to return a relative and an absolute path for different keys in the same call.

Since there are many people interested in contributing to git-repo-info, I'll leave the remaining path-related fields to them :-)

I'm CC'ing here:

- brian, who was the original author of the `print_path` [1]
- Ayush, Tian, Jayatheerth, Soutrik and Pushkar, since they expressed interested
  in contributing to git-repo-info in GSoC. (I hope that I didn't forget anyone)

This patch is based on top of master 2cc7191751 (The 8th batch, 2026-02-27) with lo/repo-leftover-bits merged.

  rev-parse: prepend `path_` to path-related enums
