x11-ssh-askpass.man.in: spell "LED" consistently

Update x11-ssh-askman manpage app-defaults paths to X11R7

Now matches actual code

Whitespace stuff; new sentence, new line; fix some xrefs; use Aq more.

Update ssh-askpass to version 1.2.0. This adds, among other changes,
teh ability to display multiples lines as the message, sth openssh
assumes and a man page.

last change backed out; this xsrc is meant for a base system that contains
the necessary pthread functions as 'weak pthread stubs' in libc
xsrc/28832 staying closed

libX11 and libXt use pthread routines, so -lpthread is needed to link

Remove "SshAskpass.ad" in clean target. This fixes the first half of
PR xsrc/25852 by Martin Husemann.

Use proper variables to define LOCAL_LIBRARIES, and set DEPLIBS as well.
Fixes build error on NOPIC ports.

Apparently missing argument for fprintf(3).

Install all of the app defaults examples into
/usr/X11R6/share/examples/ssh-askpass.

OpenSSH -> SSH

Tweak for NetBSD xsrc build environment.

Import Jim Knoble's x11-ssh-askpass, version 1.0, for use
with ssh-add(1).
