Remove unused option normalization.

This program only really accepts one short argument, `-h`, so this
extra complexity isn't necessary.

-# The first loop, even though it uses 'optstring', will NOT check if an
-# option that takes a required argument has the argument provided. That must
-# be done within the second loop and case statement, yourself. Its purpose
-# is solely to determine that -oARG is split into -o ARG, and not -o -A -R -G.

-# option string, for short options.

-# Very much like getopts, expected short options should be appended to the
-# string here. Any option followed by a ':' takes a required argument.
-#
-# In this example, `-x` and `-h` are regular short options, while `o` is
-# assumed to have an argument and will be split if joined with the string,
-# meaning `-oARG` would be split to `-o ARG`.
