From c0868d959d38d1178acd8b1cba14a0944ea0c2a4 Mon Sep 17 00:00:00 2001 From: William Casarin Date: Sat, 4 Apr 2020 13:41:32 -0700 Subject: [PATCH] emacs/tree: add notmuch-tree-goto-matching-message This function captures some common logic when jumping to matching messages in notmuch-tree mode. We also add a new return value (t or nil), that indicates if there was a next matching message in the thread to show.
