   2: **  PUT CHARACTER
   3: **
   4: **	This routine just calls putchar normally, unless the character
   5: **	to be printed is a control character, in which case the octal
   6: **	equivalent is printed out.  Note that tab, newline, and so
   7: **	forth are considered to be control characters.
   8: **
   9: **	Parameters:
  10: **		ch -- the character to print.
  11: **
  12: **	Returns:
  13: **		nothing.
  14: **
  15: **	Side Effects:
  16: **		none
  17: **
  18: **	Requires:
  19: **		putchar
  20: **
  21: **	Called by:
  22: **		printatt
  23: **		prargs
  24: **		(maybe others?)
