This adds hidden counter-flags for the following:
-L/--follow [--no-follow]
--hidden [--no-hidden]
--no-ignore [--ignore]
--no-ignore-parent [--ignore-parent]
--no-ignore-vcs [--ignore-vcs]
--no-messages [--messages]
--search-zip [--no-search-zip]
--sort-files [--no-sort-files]
--text [--no-text]
In the above list, the counter-flags are in brackets.
While these flags are hidden, we document the counter-flags in the
documentation for the flags they are countering.
