vnews 2.10.2 handling of SIGTSTP

[Mister Snuffle-upagus]

I have not looked into the code to see why, but vnews does not handle
Control-Z's too well when invoked from /bin/sh.  (4.1 BSD 11/780).

This bit me the other day when I was doing a reply to an article, control-z'd
vi by accident, and got stuck doing nothing.  I had to log in at another
terminal and send SIGCONTIN (signal 19) at each process in turn until the
shell came back.

The way to handle this is to check what the incoming status of SIGTSTP is.
If it is SIG_IGN, then pass that on to the children (i.e. vi).  Since the
BSD /bin/sh ignores this signal, vnews will be set to ignore it too when
it cranks up.

I hope that this will be fixed for 2.10.3.
