       2: **  SET FLAG
       3: **
       4: **	This routine sets flags from argv.  You give arguments
       5: **	of the argv, the flag to be detected, and the default
       6: **	for that flag (if it is not supplied).  The return value
       7: **	is the flag value.   For example:
       8: **		setflag(argv, 'x', 2);
       9: **	returns zero if the "-x" flag is stated, and one if the
      10: **	"+x" flag is stated.  It returns 2 if the flag is not
      11: **	stated at all.
      12: **
      13: **	History:
      14: **		8/15/79 (eric) (6.2/7) -- changed to take -1
      15: **			or 0 as argv[argc].
