It was switched for variable argument support in bpl21.  This was part of
a general effort (by George) to clean up buffering in CircleMUD.  Note
that the formerly common idiom

  /* For pre-bpl21.  buf is global, a, b, c are locals. */
  sprintf(buf, "%s %d %d\r\n", a, b, c);
  send_to_char(buf, ch);

was undesirable both for its use of a global buffer and the failure to
check for overflow.  With the change, send_to_char() is both safer
(because the buffer handling is internal and checked with snprintf()) and
more convenient:

  /* bpl21 and up. */
  send_to_char(ch, "%s %d %d\r\n", a, b, c);
