From bcb5d3adbe57ead05a829e5144c2ba1dc465865f Mon Sep 17 00:00:00 2001 From: "Devin J. Pohly" Date: Wed, 21 Feb 2018 23:29:41 -0600 Subject: Move terminal-related selection logic into st.c The front-end determines information about mouse clicks and motion, and the terminal handles the actual selection start/extend/dirty logic by row and column. While we're in the neighborhood, we'll also rename getbuttoninfo() to mousesel() which is, at least, less wrong. Signed-off-by: Devin J.
