+Subject: [PATCH] Fix backward selection
+
+When selecting with the mouse in backward direction, the selection takes
+only one char.
+This bug was introduced with the commit:
+e4c7bfd scrollback/selection: refactor scrollback and selection code
+
+So store the first click to its own selection (sel_begin) and then when
+the target change, make sure to correctly order sel_start and sel_end.
