Bugfix: Fix problems revealed when working on FSS Extended List Read.

Be sure to explicitly check data->objects.used is non-zero when counting total.

The Basic List and Extended List Object names, when being selected (via the --select parameter), should be trimmed by default.
This is because the Basic List nd Extended List standards define an Object name as beginning after on the first non-whitespace and ending at the last non-whitespace.

Minor syntax cleanups such as replaced "if (X > 0)" with "if (X)".
