Subject: tog: "search wrapped" notifications
To: gameoftrees@openbsd.org
Date: Sun, 30 Apr 2023 14:54:48 +0300

In continuation of this thread:
https://marc.info/?l=gameoftrees&m=167606517310115&w=2

Inlined patch adds "search wrapped" and "diff navigation wrapped" for
searches and file/hunk diff navigation.

It also makes the notification highlighted with wstandout(), since in my
testing on large screen it helps to notice the wrap arounds.
