--ultra automatically triggered with --long and --patch-from

the purpose of --ultra is to make the user explicitly opt-in
to generate very large window size (> 8 MB).

The agreement to generate very large window size is already implicit
when selecting --long or --patch-from.

Consequently, `--ultra ` is automatically enabled when `--long` or `--patch-from` is set.
