Add ANSICON_WRAP for programs that expect wrap

Some programs (notably less) rely on the right margin performing the
wrap.  Add such programs to the ANSICON_WRAP environment variable to
stop ANSICON suppressing the newline.

+    ANSICON will detect when a line wraps at the right margin and suppress a
+    following newline.	Some programs detect the wrap themselves and so the
+    following newline is actually for a blank line; use the ANSICON_WRAP
+    variable to indicate as such (see ANSICON_API below).
+
     My version of WriteConsoleA will always set the number of characters writt-
     en, not the number of bytes.  This means writing a double-byte character as
     two bytes will set 0 the first write (nothing was written) and 1 the second
