people, i've been under the weather for days and will probably be for a few more.
new  and TEMPORARY meds dont like me, ugh.

can anybody clue me in why the followin joinline program fails to catch if argc == 1?

 * simple prog to join all | very nearly all lines of a text file that 
 * make up one paragraph into one LONG line.  
 * paragraphs are delimiated by a single \n break.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

main(int argc, char argv[])
   char buf[65536];

   if (argc == 1)
	printf("Usage: %s < file > newfile\n", argv[0]);
	exit (-1);
   while (fgets(buf, sizeof buf, stdin) )
     if (*buf == '\n')
       fprintf(stdout, "\n\n");
       buf[strlen(buf)-1] = ' ';
       fputs(buf, stdout);
