+	  fixes bug in computation of value for %n format char

+	  Preparation for printf -v var
+	- add code to add the text printed to a `variable buffer' if -v option
+	  supplied.  The buffer grows as needed
+	- printf now takes a `-v var' option to put the output into the variable
+	  VAR rather than sending it to stdout.  It does not:
+		print partial output on error (e.g., format string error)
+		handle NULs in the variable value, as usual
