- Fix my braino in the 220835, when I used strtok(). It isn't
  applicable here, since modifies the string. Switch to strchr().
- Restore support for undocumented optional parameters of
  redir_port and redir_proto, that were disabled in 220835.
- While here, change !isalpha() checks on optinal parameters
  for isdigit().
