I re-indented the source code using indent with the following options:
indent -kr -bad -bap -nut -i8 -l80 -psl -sob -ss -ncs
There are now _no_ tabs in the source files, and all indentation is

on it's own line. Read the indent manual for more information about
what each option means.
to handle IPv6 style addresses along with the existing IPv4 and string
addresses. In addition, the hand-rolled "list" code has been replaced

that the new code does work with all the formats that will be thrown
at it.
