patch 9.1.0016: default diff highlighting is too noisy Commit: https://github.com/vim/vim/commit/124371c5a149a8c0c75c04b6c90ac11e71a0aa97 Author: Romain Lafourcade <romain.lafourcade@razorfish.fr> Date: Sun Jan 7 15:08:31 2024 +0100 patch 9.1.0016: default diff highlighting is too noisy Problem: default diff highlighting is too noisy Solution: Link diff highlighting groups to new Added/Removed/Changed, revert previous change (Romain Lafourcade) Remove diff* links added in #13776 and doc added in commit b1392be The links added in #13776 are way too noisy for the contexts in which the `diff` syntax is applied (git commits, patches, etc.). This commit: - removes those links - adds new default highlighting groups Added, Changed and Removed - links the diff highlighting groups to those new defaults - removes the doc changes - adjusts the syntax_completion test for those newly added group names Note: Changes to the default color schemes will be handled separately, by adding links to those newly created Added/Removed/Changed highlighting groups. related: #13776 closes #13825 Signed-off-by: Romain Lafourcade <romain.lafourcade@razorfish.fr> Signed-off-by: Christian Brabandt <cb@256bit.org>
