I pasted that list from aptitude's man page, at the point at which I had given
up
hope of finding the answer. It's the identical "v"-omitted list from
dpkg-query's
man page.

I was searching www and various man pages for a tabular *list* of meanings of
the
letters after finding no "v" in the dpkg*/apt* man pages. After a long period of
frustration searching for that single letter command option, I pasted into my OP
the only list I managed to find that answered the question in an apparent
comprehensive tabular list format.
Had the word "virtual" come to mind, as it did for Greg, I may have managed to
come up with an answer myself, likely in similar manner.
Is there a catalog anywhere of all Debian's package management commands?
Figuring
out which to use for any given requirement is a daunting task, with a multitude
of
similar sibling/hyphenated/plugin commands taking the place of command options,
switches and sub-commands (as with yum/dnf); as opposed to zypper, which works
virtually exclusively with switches, sub-commands and options, *all*
discoverable
by searching through a comprehensive _single_man_page_.
