+** 'auto-composition-mode' can now be selectively disabled on some TTYs.
+Some text-mode terminals produce display glitches trying to compose
+characters.  The 'auto-composition-mode' can now have a string value
+that names a terminal type; if the value returned by the 'tty-type'
+function compares equal with that string, automatic composition will
+be disabled in windows shown on that terminal.  The Linux terminal
+sets this up by default.
