From 29853b901045ff09ac8e5b48a01ebbc96fa4874d Mon Sep 17 00:00:00 2001 From: Alexander Gavrilov Date: Sun, 31 Aug 2008 01:02:56 +0400 Subject: [PATCH] git-gui: Reimplement and enhance auto-selection of diffs. Generalize the next_diff system, and implement auto-reselection for merge tool resolution and reshow_diff. Also add auto-selection of diffs after rescan, if no diff is already selected. New auto-select rules: - Rescan auto-selects the first conflicting file, or if none a modified tracked file, if nothing was selected previously. - Resolving a conflict auto-selects the nearest conflicting file, or nothing if everything is resolved. - Staging the last remaining hunk auto-selects the nearest modified staged file. - Staging a file through its icon auto-selects the nearest file.
