Add new option --with-screen instead on --with-slang,
|

--with-included-slang and --with-ncurses. Only allow
|
||||
--with-termcap is using the included S-Lang library.
|

* aclocal.m4: Corresponding changes.
|
||||
|
||||
* syntax/mail.syntax: Replace "wholechars right" and "wholechars
|
||||
left" with single "wholechars".
|
||||
* syntax/nroff.syntax: Likewise.
