+Subject: [PATCH] Revert "snapshot of project "xterm", label xterm-347i"
+
+The changes introduced in xterm-347i cause a regression in tmux's
+"horizontal" (read: one pane on the left, and one pane on the right)
+splitting behavior, making the graphical output unstable and unreadable.
+
+This reverts commit 7914e2709aa7836bfb61cd21f83880d4b7d44d8d.
