[RFC PATCH 0/2] parse-options: improve early option scanning

[Azuama Odinaka Maximus <azuama69@gmail.com>]

This RFC series shares my progress on improving early option
scanning in rev-list and exploring a reusable scanning API.

The first patch updates rev-list's early scan to account for
options that consume arguments.

The second patch introduces a generic early option-scanning API
with tests, as a step towards a more reusable solution.

The rev-list patch still uses an initial hardcoded option list,
which I recognise is fragile based on the review feedback.
I am investigating how to avoid this limitation and how best
to integrate revision-option argument parsing without triggering
unwanted parsing side effects.

I would appreciate feedback on the direction of this work,
particularly the API design and its integration with revision
option parsing.
