thanks for newsrecover

Thanks to Alan Watt for newsrecover.  We too have had problems
with .nindex disappearing.  In the past I have just gone to
our most recent backup.  We have a vax and a pdp11/70, but
it only seems to happen on our 11/70.  Can anybody verify that
observation.  

I had to make some changes to compile newsrecover on our PWB systems
(I haven't yet had an "opportunity" to try it out).
These are embodied in the following:

Change 
#include <stat.h>
#include <dir.h>

to

#ifdef PWB 
#   include <sys/dir.h>
#   include <sys/stat.h>
#   define  index strchr
#   define  rindex strrchr
#   define  dir    direct
#else
#   include <dir.h>    
#   include <stat.h>
#endif
