If you keep searching down for ::Verbose in the manpage itself, you get
to this:

  When combined with -v or a non-zero value for
  Aptitude::CmdLine::Verbose, this displays the entire chain of
  dependencies that lead each package to be installed. For instance:

But the full and authoritative place for the configuration values where
everything is nicely explained is here (or aptitude-doc-${lang}):


  Option: Aptitude::CmdLine::Verbose
  Default: 0
  Description: This controls how verbose the command-line mode of
  aptitude is. Every occurrence of the -v command-line option adds 1 to
  this value.

If nothing else, the default value should give a good idea of what type
the variable expects to get: integers.

It is not a good idea to start to duplicate the information everywhere
in manpage and guide (and in some cases on-line quick help and in-source
messages) -- it takes at least twice the work and can easily lead to
being out of sync (I've been fixing many such cases lately), so marking
as +wontfix and closing.
