=== Hiding vertical borders
You can hide vertical borders adjacent to the screen edges using
+hide_edge_borders+. This is useful if you are using scrollbars. This option is
disabled by default.
+hide_edge_borders+. This is useful if you are using scrollbars, or do not want
to waste even two pixels in displayspace. Default is none.
*Syntax*:
----------------------------
hide_edge_borders <yes|no>
hide_edge_borders <none|vertical|horizontal|both>
----------------------------
*Example*:
----------------------
hide_edge_borders yes
hide_edge_borders vertical
----------------------
=== Arbitrary commands for specific windows (for_window)
