Subject: [PATCH] (smerge-refine-region): Add support for a virtual "other
 cursor"
Date: Mon, 16 Jun 2025 07:11:24 -0400

[Message part 1 (text/plain, inline)]

Tags: patch

The patch below adds support to `smerge-refine-region` for keeping
a kind of "virtual cursor" that shows the "corresponding" point in the
other part of a diff.  I.e. it shows where
`smerge-refine-exchange-point` would jump.

The patch is somewhat incomplete in that it works only after the user
explicitly calls `M-x cursor-sensor-mode RET` (and it lacks a NEWS entry).

I'm thinking of adding a global `smerge-refine-shadow-cursor-mode` minor
mode to enable this feature and am thinking of enabling it by default.

Comments, objections?
