Subject: bug#62671: 28.2; diff-mode highlighting bug
Date: Wed, 05 Apr 2023 00:17:34 +0200 [thread overview]

Consider the following test.diff file:
--- a
+++ b
@@ -1,1 +1,1 @@
-0123456789
+.0123456789.0123456789xx
--- a
+++ b
@@ -1,1 +1,1 @@
-0123456789
+.0123456789.0123456789
When I open it with "emacs --no-site-file -Q test.diff", the
highlighting of the first diff is incorrect: the following
characters are highlighted:
-0123456789
+.0123456789.0123456789xx
^^^^^^^ ^^^^ ^^^
The highlighting in the second diff is correct:
-0123456789
+.0123456789.0123456789
^^^^^^^^^^^^
I've also attached a screenshot.
