apt-listchanges runs with the hook: DPkg::Pre-Install-Pkgs

aptitude does not call this directly, however I suspect that this is
part of the code in apt downloading .deb and installing the files.

Since presumably there's nothing to download, the DPkg::Pre-Install-Pkgs
is called almost immediately.


When aptitude doesn't need to do anything "gg" shouldn't perform any
action, but it currently does.  (On the other hand, if there's nothing
to do, you as "user" wouldn't have any reason to press "gg" either).


About hiding the output of hooks, in general I think that it's
undesirable.  Maybe it should be presented inside an error message
(there are bugs open about that).  But if it silently ignores the
output, one wouldn't notice when real problems arise.


Cheers.
