+Subject: [PATCH] Remove a BSD-ism.
+
+CTRL('L') is a BSD-ism.  CTRL() is defined in sys/ttydefaults.h
+which does not always exist.  Instead of adding scons tests for
+needing CTRL() and its include files just replace with a simple
+constant.
+
+Needed for musl and found by Baruch Siach <baruch@tkos.co.il>
