[RFC PATCH 0/1] add -p: support discarding hunks

[Luiz Campos <luizedc1@gmail.com>]

Hi,

This is an RFC for adding a 'discard hunk' action to `git add -p`.

Currently, when using `git add -p`, users can stage or skip hunks,
but cannot discard unwanted changes directly from the working tree.
This often leads to repeatedly skipping the same hunks across
multiple passes.

This patch introduces a new 'x' action to discard the current hunk
by reverse-applying it to the working tree.

This idea was previously discussed on the mailing list:
https://lore.kernel.org/git/X%2FiFCo0bXLR%2BLZXs@coredump.intra.peff.net/t/#m0576e6f3c6375e11cc4693b9dca3c1fc57baadd0

Open questions:
- Should discard happen immediately or be deferred until patch application?
- Are there edge cases involving overlapping hunks or edited hunks?

Feedback is very welcome.

Thanks,
Luiz
