* 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
