  *      Erik W. Troan, which they placed in the public domain.  I don't know
  *      how much of the Johnson/Troan code has survived the repeated rewrites.
  * Other credits:
- *      simple_itoa() was lifted from boa-0.93.15
  *      b_addchr() derived from similar w_addchar function in glibc-2.2
  *      setup_redirect(), redirect_opt_num(), and big chunks of main()
  *        and many builtins derived from contributions by Erik Andersen
