From exec(3): “The list of arguments must be terminated by a NULL
pointer, and, since these are variadic functions, this pointer must be
cast (char *) NULL.”

This prevents crashes on 64-bit systems, where 0 is a 32-bit integer
and (char *) NULL is a 64-bit pointer.

Previously when the EDITOR environment variable is set to a command
with arguments, such as ‘emacsclient --alternate-editor emacs’, ldapvi
would fail to launch the editor:

$ ldapvi
     26 entries read
error (misc.c line 180): No such file or directory
editor died
error (ldapvi.c line 83): No such file or directory

Also setting PAGER to "less -s" or similar had the same effects
when you use Action? (v) view LDIF changes or other commands
that invoke $PAGER.
