Bugfix: The -t/--total in iki_read is confusing and allow for --total with --whole.

Bugfix: The -t/--total in iki_read is confusing and allow for --total with --whole.

The `--total` parameter should print the total number of IKI Variables.
The `--line` parameter is selecting based on the line as if the `--whole` parameter is based (even when it is not).
This makes little sense when in the `--content` that is the default behavior.

This solves part of that confusion by focusing on the `--total` parameter.

Using the `--whole` should also print the total number of lines rather than total number of Variables.

I will need to follow this up with runtime tests.
There are none at this time so a separate commit is needed to add all of the appropriate tests.
